  • What’s CNC machining

    CNC machining, or Computer Numerical Control machining, is a manufacturing process that involves the use of computer-controlled machines to produce parts and components from a variety of materials. It is a type of subtractive manufacturing process, which means that material is removed from a larger block or piece of material to create the desired shape.
     
    The CNC machining process typically involves the following steps:
     
    Design: A 3D model of the part or component is created using computer-aided design (CAD) software.
     
    Programming: The 3D model is then imported into a computer program that generates the instructions for the CNC machine to follow. These instructions include the tool paths, cutting speeds, and other parameters that the machine will use to create the part.
     
    Setup: The material to be machined is mounted onto the machine, and the cutting tools are installed.
     
    Machining: The CNC machine follows the instructions from the program to cut and shape the material to create the desired part or component.
     
    Finishing: Once the part is machined, it may require additional finishing processes such as sanding, polishing, or coating to achieve the desired surface finish.
     
    CNC machining is used to create parts and components for a wide range of industries, including aerospace, automotive, medical, and electronics.

With the help of CAD (Computer-Aided Design) software, engineers and designers can create highly accurate 3D models that can be used to create CNC programs that control the movements of the machine tools. This level of precision and control has revolutionized the manufacturing industry, making it possible to produce complex parts with high accuracy and consistency.
     

  • What’s 3D printing

    3D printing is a type of manufacturing process that involves creating a three-dimensional object by building it layer by layer. In this process, a digital model is first created using specialized software, and then sent to a 3D printer. The printer uses the digital model as a guide to deposit thin layers of material, such as plastic, metal, or composite materials, on top of one another until the final object is complete.
     
    3D printing has a wide range of applications in many fields, including product design, engineering, architecture, medicine, and art. It has become increasingly popular due to its ability to quickly and efficiently produce prototypes and customized products, as well as its potential to reduce waste and costs compared to traditional manufacturing methods.
     
    GoodTech MFG company provides excellent 3D printing jobs, short lead time, and reasonable prices. Contact us for more details. 
     
    The process of 3D printing begins with a digital model, which can be created using computer-aided design (CAD) software, or obtained from a 3D scanner. The digital model is then sliced into thin layers, typically ranging from 0.1 to 0.3 millimeters in thickness. These layers are then sent to the 3D printer, which uses them as a guide to deposit material layer by layer until the final object is complete.
     
    There are several different types of 3D printing technologies, but some of the most common ones include:
     
    Fused Deposition Modeling (FDM): This is the most widely used 3D printing technology, in which a plastic filament is melted and extruded through a heated nozzle, which moves in the X, Y, and Z axes to deposit the material layer by layer.
     
    Stereolithography (SLA): In this process, a liquid resin is cured by a UV laser, which selectively hardens the material in the desired areas to form the object.
     
    Selective Laser Sintering (SLS): In SLS, a laser selectively fuses powdered material (such as nylon, polyamide, or metal) to create the final object.
     
    Digital Light Processing (DLP):  is a 3D printing technology that uses a digital projector to selectively cure liquid resin layer by layer to create a 3D object. The process is similar to Stereolithography (SLA) in which a UV laser is used to selectively cure a liquid resin. However, in DLP, a digital projector is used instead of a laser.
     
    Multi Jet Fusion (MJF): is a 3D printing technology developed by HP that uses a unique process to selectively fuse layers of powdered material with the help of an energy source and a fusing agent.
     
    Once the 3D printer has finished building the object, it may require some post-processing, such as removing support structures (if any were used during the printing process), sanding, or painting.
     
    There are many applications of 3D printing, ranging from rapid prototyping and product development to customized manufacturing and even creating replacement body parts in medicine. 3D printing can also be used for creating complex geometries and intricate designs that would be difficult or impossible to achieve using traditional manufacturing methods.
     
    Some of the advantages of 3D printing include the ability to create complex designs, rapid prototyping, lower cost for small-batch production, and the ability to customize products to meet specific needs. However, there are also some limitations to 3D printing, including the relatively slow speed of printing, the limited range of materials that can be used, and the need for post-processing.
     
     
    History of 3D printing
     
    The history of 3D printing dates back to the 1980s, with the development of the first 3D printing technology, Stereolithography (SLA), by Chuck Hull, the founder of 3D Systems. Hull filed a patent for the SLA process in 1986, and in 1988, he and his company introduced the first commercial 3D printer.
     
    In the 1990s, other 3D printing technologies emerged, including Selective Laser Sintering (SLS) and Fused Deposition Modeling (FDM), which was developed by Scott Crump, the founder of Stratasys. FDM technology, which extrudes melted plastic through a heated nozzle to build up a 3D object layer by layer, became one of the most widely used 3D printing technologies for prototyping and low-volume production.
     
    In the early 2000s, 3D printing became more accessible to the wider public, with the introduction of lower-cost desktop 3D printers. These printers used FDM and other technologies to create 3D objects, and they quickly gained popularity among makers, hobbyists, and educators.
     
    In the following years, 3D printing technology continued to advance rapidly, with the development of new materials, printing processes, and applications. This included the introduction of Metal 3D Printing, using processes such as Direct Metal Laser Sintering (DMLS), Selective Laser Melting (SLM), and Electron Beam Melting (EBM) to build up metal parts layer by layer.
     
    More recently, new 3D printing technologies have emerged, such as Multi Jet Fusion (MJF), developed by HP, which uses a unique process to fuse layers of powdered material with the help of an energy source and a fusing agent. Additionally, advancements in bioprinting have allowed for the creation of living tissue, opening up possibilities for medical applications.
     
    Today, 3D printing is widely used in industries such as aerospace, automotive, healthcare, and architecture, as well as in the arts, education, and consumer markets. The technology has transformed the way products are designed, developed, and produced, and it continues to be a driving force for innovation and creativity in many fields.
     

  • What’s gravity casting

    Gravity casting is a casting process that involves the use of gravity to fill a mold with molten metal or alloy. In this process, the molten material is poured into a mold cavity from a container, which is positioned above the mold. The force of gravity pulls the liquid metal or alloy into the mold, filling it completely.
     
    The mold used in gravity casting is typically made of a material such as sand, ceramic or metal. The molten material is poured into the mold through a small opening called a sprue, which is connected to the container. The molten material then flows into the mold cavity, filling it completely.
     
    Gravity casting is commonly used for the production of high-quality, small to medium-sized parts with a wide range of shapes and complexity. It is a cost-effective and efficient method of casting, as it requires minimal equipment and can produce large quantities of parts quickly. The process is widely used in the manufacturing of automotive and aerospace components, as well as in the production of household items such as cookware and faucets.
     
    History of Gravity Casting
     
    Gravity casting has been used for centuries and its history can be traced back to ancient civilizations such as Egypt, Greece, and Rome. In these early societies, metal objects were made by pouring molten metal into simple molds made of sand, clay or other materials, using gravity to fill the mold.
     
    In the 19th century, the process of gravity casting was refined with the introduction of better materials, molds, and equipment. The development of industrial processes and machinery during the 20th century further improved the quality and efficiency of the process.
     
    During World War II, gravity casting was widely used for the production of military equipment and components. The increased demand for high-quality and precise casting during this time led to the development of new alloys and manufacturing techniques.
     
    In the post-war period, the growth of the aerospace industry and the demand for lightweight, high-strength components led to further advancements in gravity casting technology. This included the development of new materials, such as titanium and aluminum, as well as new methods of mold making and casting.
     
    Today, gravity casting is a widely used manufacturing process in many industries, including automotive, aerospace, and consumer goods. It remains an important method for producing high-quality and complex parts in a cost-effective and efficient manner.
     
     
    Comparison of sand mold VS metal mold for gravity casting
     
    Both sand molds and metal molds can be used in gravity casting, but they differ in several important ways.
     
    Cost: Sand molds are generally less expensive than metal molds because they are easier to make and can be reused multiple times. Metal molds, on the other hand, require more time and effort to make and are more expensive to produce.
     
    Quality: Metal molds are typically more precise and produce higher-quality castings than sand molds. This is because they can be designed and machined to very precise specifications, whereas sand molds are more prone to dimensional variation and surface defects.
     
    Complexity: Sand molds are generally better suited for casting simple shapes and designs, while metal molds are better suited for more complex shapes and intricate details. This is because metal molds can be machined to very precise tolerances and can capture fine details, while sand molds are limited by the properties of the sand and the molding process.
     
    Production volume: Sand molds are better suited for low-volume production runs, while metal molds are better suited for high-volume production runs. This is because sand molds can be easily and quickly produced, while metal molds require more time and effort to make but can produce many more castings before they need to be replaced.
     
    Overall, the choice between sand molds and metal molds for gravity casting will depend on the specific requirements of the part being produced, as well as the production volume and cost considerations. Sand molds are generally more cost-effective and suitable for simpler shapes and lower production volumes, while metal molds are more precise and suitable for more complex shapes and higher production volumes.

  • What’s the difference between CNC machined prototypes and 3D printed prototypes

    CNC machined prototypes and 3D printed prototypes are two common methods used for creating prototypes in product development. Here are some key differences between the two:
    Manufacturing Process:
     
    CNC (Computer Numerical Control) machining is a subtractive process where material is removed from a solid block of material using cutting tools that are controlled by a computer program. The cutting tools are typically rotary and can be made of a variety of materials including carbide, high-speed steel, and diamond. The CNC machine follows the design created in a CAD (Computer-Aided Design) software program, which is converted into G-code that the CNC machine reads to execute the cutting operations.
     
    3D printing, also known as additive manufacturing, is a process that builds objects layer by layer using a 3D digital model as a guide. The 3D printer creates the object by melting or softening material, then depositing it in layers that gradually build up to form the final shape. 3D printers can use a variety of materials, including plastics, metals, ceramics, and composites.
     
    Material Options:
    CNC machines can work with a wide range of materials, including aluminum, steel, copper, brass, zinc, titanium, ABS, PC, POM, PA, PMMA, PP, and other composites. This allows for more flexibility when it comes to selecting the right material for the prototype based on its properties, such as strength, durability, and heat resistance. CNC machines can produce parts with tight tolerances and high precision.
     
    3D printers, on the other hand, are limited in the materials they can use. They typically work with plastics, such as ABS (Acrylonitrile Butadiene Styrene) and PLA (Polylactic Acid), or resins for SLA (Stereolithography) printers. Some printers can use metals, such as aluminum, steel, and titanium, but the process is more complicated and requires more expensive equipment.
     
    Surface Finish:
    CNC machined parts generally have a smoother surface finish than 3D printed parts. This is because the cutting tools used in CNC machining can create precise cuts that result in a polished surface. CNC machining can produce parts with a surface finish that doesn't require any additional post-processing or sanding.
     
    3D printed parts, however, have a textured surface finish that is a result of the layer-by-layer process used in additive manufacturing. This means that 3D printed parts usually require additional post-processing, such as sanding or polishing, to achieve a smooth surface finish.
     
    Cost:
    CNC machining is generally more expensive than 3D printing, especially for small production runs or single prototypes. This is because CNC machines require more specialized equipment and trained operators to set up and run the machine. The cost of the material used in CNC machining can also be higher due to the higher precision and accuracy required.
     
    In comparison, 3D printing is generally more affordable, especially for small or intricate parts. The cost of the material used in 3D printing is typically lower than that used in CNC machining, and 3D printers can run unattended, reducing the labor costs associated with the manufacturing process.
     
    In summary, CNC machining and 3D printing both have their advantages and disadvantages when it comes to creating prototypes. CNC machining is better for producing parts with tight tolerances, a smooth surface finish, and a wider range of material options. 3D printing is better for producing complex geometries, and is generally more affordable for small production runs.

  • Why 3D printing so popular for prototyping

    3D printing has become popular for prototyping due to several reasons:
     
    Speed: 3D printing enables rapid prototyping, allowing designers and engineers to quickly produce physical prototypes of their designs within hours or days. This is much faster than traditional prototyping methods, such as CNC machining or injection molding, which can take days or weeks to produce a prototype.
     
    Cost-effectiveness: 3D printing is generally less expensive than traditional prototyping methods, as it requires less material and labor. This makes it more accessible to small businesses and individuals who may not have the resources to invest in expensive equipment or materials.
     
    Customization: 3D printing allows for the creation of complex shapes and geometries that would be difficult or impossible to produce with traditional manufacturing methods. This enables designers to create unique and innovative products that may not have been possible otherwise.
     
    Iterative prototyping: 3D printing allows for quick and easy design iterations, enabling designers to make changes and adjustments to their prototypes as needed. This can lead to faster and more efficient design iterations, ultimately resulting in a better final product.
     
    On-demand production: 3D printing enables on-demand production, which means that prototypes can be produced as and when they are needed. This is particularly useful for small businesses or individuals who may only need a few prototypes and do not want to invest in large-scale manufacturing.
     
    Overall, the speed, cost-effectiveness, customization, iterative prototyping, and on-demand production capabilities of 3D printing have made it a popular choice for prototyping. These benefits have helped to accelerate the product development process, reduce costs, and improve the quality of final products.

  • What’s die casting

    Die casting is a manufacturing process used to produce metal parts with high precision and quality. In this process, molten metal is injected into a mold, also known as a die, under high pressure. The mold is typically made of two halves that are fastened together and designed to create the desired shape of the part. The molten metal is then forced into the mold, where it cools and solidifies into the desired shape. Once the metal has cooled and solidified, the two halves of the mold are separated and the finished part is removed.
     
    Die casting is commonly used for manufacturing parts made of non-ferrous metals, such as zinc, aluminum, and magnesium, due to their low melting points and high fluidity. The process allows for the production of parts with intricate shapes and fine details, and can be used to create parts with thin walls and complex geometries. It is commonly used in industries such as automotive, aerospace, and electronics, where high quality and precision are critical.

    What’s-vacuum-casting01
     
    The first vacuum casting machines were developed in the 1950s, and they were used to produce parts made of aluminum and magnesium alloys. Over time, the technology evolved to allow for the production of a wider range of materials, including stainless steel, titanium, and various plastics.
     
    Today, vacuum casting is widely used in a variety of industries, including automotive, medical, and consumer goods. The process allows for the creation of highly accurate and detailed parts, and it is often used for small-scale production runs or for prototyping new designs.
     
    What are the advantages of vacuum casting?
     
    One of the primary benefits of vacuum casting is its cost-effectiveness, particularly for small production runs. Traditional injection molding requires expensive tooling and equipment, which can make it prohibitively expensive for small-scale production. Vacuum casting, on the other hand, requires only a single mold, which can be quickly and easily produced using 3D printing or CNC machining. This makes the process much more accessible and affordable for small businesses and startups.
     
    Another advantage of vacuum casting is its flexibility. Because the molds are relatively easy and inexpensive to produce, it is possible to make design changes quickly and easily. This allows for a more iterative and agile design process, where multiple iterations of a product can be quickly and affordably produced, tested, and refined.
     
    Vacuum casting is also a great option for creating prototypes or small production runs for market testing. Because the process is so flexible and cost-effective, it is possible to produce a small number of parts quickly and affordably, without committing to the expense of full-scale production. This allows companies to test the market demand for a product before committing to a large production run.
     
    Of course, vacuum casting does have its limitations. Because the molds are made from silicone, they can only withstand a limited number of cycles before they begin to degrade. Additionally, the process is not ideal for creating parts with thick walls or large volumes, as the liquid plastic may not fully fill the mold. For these applications, traditional injection molding may be a better option.
     
    In conclusion, vacuum casting is a versatile and cost-effective manufacturing process that is particularly well-suited for small production runs of high-quality plastic parts. Its flexibility and affordability make it a great option for prototyping and market testing, as well as for small businesses and startups. While it does have its limitations, the benefits of vacuum casting make it an attractive option for many applications, particularly for those requiring complex geometries or fine details.
