What is the Vacuum Casting?
Thevacuum casting china
Vacuum Casting Process
1. Make a silicone mold by using the master made by CNC machining and 3D printed.
2. Put the silicone mold into the vacuum molding machine.
3. Inject liquid epoxy resin and heat to cure.
4. After the curing is completed, take out the same part as the Master from the silicone mold, and one silicone mold can be used for 20 times.
Vacuum Casting is suitable for small batch production, which can greatly reduce production costs, increase production efficiency and shorten the construction period.
Applications for Vacuum Casting
It is mainly used for product copying and mold making in various industries.
Vacuum Casting Materials
We offer a wide range of material options: ABS, PP, PC, PMMA, POM, high temperature resistant materials, soft rubber, silicone rubber, etc. Varieties of materials are available to make silicone molds comparable to injection molded parts. The following pictures are rubber, PC-like material, ABS-like material, POM-like material and transparent material.
Advantages of Vacuum Casting
The cost is low and the production cycle of the product is relatively short. Less waste and processing costs are much lower than CNC machining and 3Drapid prototyping.
It is suitable for the processing and production of small batch products. After making an original version, it can be copied according to the original version, and the production efficiency is high.
Good mold operation. The soft molds after curing are all transparent or translucent, have good tensile strength, and are easy to cut and shape.
The probability of processing failure is small. As long as there is no problem with the original, the copy will naturally not go wrong.
Good repeatability. The silicone for molding has good fluidity before curing, and the fine structure and decoration of the model can be accurately maintained with vacuum defoaming.
We have the world's most advanced vacuum casting equipment, and provide post-processing lines such as polishing, painting and assembly. We can provide small batch production of small and medium-sized parts quikly. If you are looking for reliablefast prototyping service
Zinc Alloy Die Casting Zinc die casting is a metal casting process characterized by pressuring molten metal into the mold cavity. The mold cavity is created using two hardened tool steel molds that are machined to the net shape or near net shape of the zinc die casting parts. ...
