In order to adapt to the development of the market, prototype production came into being. So, what are the reasons for making prototypes? 1. Check the appearance design Prototypes are an important method for verifying product designs. Appearance prototypes allow for intuitive review, reflecting the designer&#8217;s creativity and producing it in a physical form , avoiding the drawback of &#8220;looking good in the drawing but not in the finished product . &#8220; Therefore, prototype production is a very important part in the [&hellip;]
- [How Are Plastic Pellets Used In 3D Printing? Which Is Better, Plastic Pellets Or Filaments?](https://gf-proto.com/how-are-plastic-pellets-used-in-3d-printing-which-is-better-plastic-pellets-or-filaments/): Brief Intro FDM 3D printing is one of the most widely used 3D printing technologies, and basically all FDM 3D printers use PLA and ABS filaments as printing materials. However, this situation has changed now, and some FDM 3D printers have begun to use plastic particles as printing materials. Plastic granules have always been used mainly for injection molding, including the filaments used in 3D printing, which are also made of plastic granules . When 3D printing with plastic pellets, the extrusion method and filament are slightly different. Plastic particles are placed in a funnel-shaped container and enter the melting [&hellip;]
- [The Differences Between Zinc Plating, Chrome Plating, Cadmium Plating And Nickel Plating](https://gf-proto.com/the-differences-between-zinc-plating-chrome-plating-cadmium-plating-and-nickel-plating/): Galvanized Features Zinc is relatively stable in dry air and is not easy to change color. In water and humid atmosphere, it reacts with oxygen or carbon dioxide to form oxide or alkaline zinc carbonate film, which can prevent zinc from continuing to be oxidized and play a protective role. Zinc is extremely susceptible to corrosion in acids, alkalis, and sulfides. Zinc coatings generally undergo passivation treatment. After passivation in chromic acid or a chromate solution, the resulting passivation film is less susceptible to humid air, significantly enhancing corrosion resistance. Dehydrogenation is essential for spring parts, thin-walled parts (thickness &lt; [&hellip;]
- [The Difference Between Sandblasting And Shot Blasting Surface Treatment Processes](https://gf-proto.com/the-difference-between-sandblasting-and-shot-blasting-surface-treatment-processes/): Hello everyone! Today we&#8217;ll discuss two common surface treatment techniques used in industry—sandblasting and shot peening. While their names may sound similar, their functions and applications are quite different. Let&#8217;s explain them in simple terms! Sandblasting A &#8220;Little Expert&#8221; for Cleaning and Beautification 1.What can sandblasting do? Remove rust and oil (such as rusty bolts). Clean the oxide scale (black hard shell) after heat treatment of parts. Remove burrs and roughen the surface (to facilitate subsequent painting or coloring). It can also create a matte finish (like the look of high-end electronics). 2.What kind of “sand” is used in sandblasting? [&hellip;]
- [How To Distinguish Cold-Rolled Steel And Hot-Rolled Steel In Appearance?](https://gf-proto.com/how-to-distinguish-cold-rolled-steel-and-hot-rolled-steel-in-appearance/): 1.

- [How To Calculate CNC Speed And Feed](https://gf-proto.com/how-to-calculate-cnc-speed-and-feed/): Introduction Each tool uses different processing parameters based on the material being processed. In the field of milling, tool manufacturers aim to improve processing efficiency by optimizing tool materials and developing more targeted coating technologies. By combining various elements in the materials, we can see thousands of raw materials that can be processed. To process these materials, we must know the processing properties of the material and also know how to optimize the processing. Material group to which the workpiece belongs According to ISO 531:1966 international standard, machinable materials are divided into 6 categories, namely: P represents steel material;M represents [&hellip;]
- [The Advantages Of Molten Core Injection Molding](https://gf-proto.com/the-advantages-of-molten-core-injection-molding/): The basic principle of fusible core injection molding is to first use a low-melting-point alloy to cast a fusible core, then place the fusible core as an insert into the mold for injection molding. After cooling, the part containing the core is taken out of the mold cavity, and then heated to melt the core to form a hollow product. When plastic parts with complex shapes that are difficult to demould are to be molded, such as automobile fuel pipes and intake and exhaust manifolds, fusible core injection molding can be used. The process of fusible core injection molding technology [&hellip;]
