Plastic Rapid Prototyping At Kesu Hardware, we provide one-stop manufacturing service for plastic rapid prototype. Specialize in various processes: silicone molding or vacuum casting, 3D printing, CNC machining and plastic injection molding etc. Kesu Hardward has considerable experience in plastic rapid prototype.
Silicone Mold
Silicone Mold
Silicone Molding is a common used machining solution for plastic rapid prototype. Compared with other solutions, the silicone molding is very fast, cheap and has a very low failure rate. One silicone mold could produce about 20 pieces of prototypes.
Available Material: ABS, PP, PC, PMMA, POM, Soft Rubber, Silicone Rubber, Heat-resistant material, etc.
Silicone Molding Processing Steps.
A. Prototype
The prototype need be made before make the silicone mold. The prototype could be machined by CNC, and the material could be the common material such ABS.
B. Silicone Mold
Making the silicone mold after the prototype was ready.
Waiting about 8 hours for drying, then cut the silicone mold and take out the prototype. At this time the silicone mold is ready.
C. Injection
Injecting the liquid material to silicone mold, it’s completed if the part is dry.
The capability of silicone mold is about 20 times.
CNC (5Axis Machined)
CNC (5Axis Machined)
The technology of CNC machining is very mature and is widely used in metal rapid prototype. The appearance and accuracy of CNC rapid prototyping are great, which is common used in plastic rapid prototyping.
The advantage of CNC rapid prototyping.
The information which expressed in the drawings could be reflected by CNC accurately. At the same time, the appearance quality of CNC prototype is very high, which is especially obvious after the surface finish, such as painting or silk screen printing. The product of CNC rapid prototyping will be much more glamorous than the one which is made by tooling. Hence, CNC rapid prototyping is becoming more and more popular in rapid prototyping.
Kesu Group has rich experience in CNC machining, especially in 3+2 machining and 5-axis machining, which could provide great help for CNC rapid prototyping services.
3D Printing (SLS Nylon)
3D Printing (SLS Nylon)
3D Printing is very popular in the plastic rapid prototyping. This technology is based on the digital model files, and will use adhesive plastic powder for material, and will build the structure via layer-by layer printing. 3D Printing is realized via the digital technology material printer. There are many different technology or method in 3D printing, such as SLA, SLS, MJF etc. Their difference is on the available material, and the way to build the layer when create parts.
Available Material of 3D printing: Nylon(White), Resin,ABS, PC.Rubber etc.
Plastic Injection Molding
Plastic Injection Molding
Plastic Injection Molding is very popular for the mass production of plastic parts.
Usually, the rubber injection and plastic injection will be used for products. Injection molding machine is the main molding equipment that uses plastic tooling molds to make plastic products to various shapes. Injection molding is realized by injection molding machines and molds.
