What is sheet metal prototype processing?
Sheet metal processing refers to the processing technology of sheet metal, and sheet metal parts are thin metal parts.The sheet metal process is an induction cold-working hand plate manufacturing process for metal sheets (usually below 6mm), including shearing, punching/cutting/compounding, folding, welding, riveting, splicing, forming (such as car body), etc.It is plastically deformed by craftsmanship or die stamping to form the desired shape and size, and can be further welded or a small amount of mechanical processing to form more complex parts, such as chimneys, iron stoves, and car shells commonly used in life.The obvious feature is the same thickness of the same part.The three most important processes of sheet metal processing are shearing, punching/cutting, and folding.

The processing of vacuum casting prototype
The processing of vacuum casting prototype
We usually use CNC maching to processing prototype ,but the CNC tooling is hard , can only process hard material.So if customer need to make rubber product ,we will not be able to use CNC machining .In that time ,we will use vacuum casting to process.vacuum casting is the best way to make rubber product in small quantity.So how vacuum casting to process a prototype?
1,programming.
2,make a mold.
3,Pour the liquid soft rubber material into the mold and take it out after cooling.
4,surface finish:
If those rubber product need to do color,there have two way to make color.one is painting after the product out of mold .Another is the color and the product out of mold together.This mean mix the color powder andrubber materials required by the customer into the mold, and take them out after cooling.
At this time, the product comes with its own color when it comes out of the mold. But the price will be more expensive than painting.
The surface of the vacuum casting product is smooth, and generally does not need manual processing. Which can save manual processing time.
If you have rubber products to make, please contact E-make. We are a rapid prototyping manufacturer in China, with over 10 years of experience in CNC,3D printing, vacuum casting and injection molding die-casting prototypes. We can quickly and cheaply produce high quality parts and prototype for you.
What Surface Finish Can Be Used For Aluminum Parts?
What Surface Finish Can Be Used For Aluminum Parts?
1.Sand blasting
Sand blasting is a process that using the impact of the high-speed sand flow to clear and coarsen the metal’s surface,which can improve the mechanical property of the parts’ surface and Fatigue resistance.
2.Polishing
Polishing is a process that reducing the roughness of the parts’ surface to make the parts with bright and smooth appearance by the mechanical, chemical or electrochemistry.
The main polishing process is mechanical polishing,chemical polishing and electrolytic polishing.
The aluminum parts can be close to the mirror finish of the stainless steel after mechanical polishing and electrolytic polishing.
3.Wire drawing
Wire drawing is a metal working process used to reduce the cross section of wire by pulling it through a series of dies.
4.Anodizing
Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.Anodizing not only can solve the problems about the aluminum’s surface hardness and anti-abrasion,but also extend the service life of aluminum.
