The technology of Vacuum Casting relies on prototype (SLA model, 3D print samples, CNC parts etc.)to create silica gel module and duplicate under the vacuum state .This technology can achieve the lower costs for small batch production than injection tooling, meanwhile meet function test, marketing, approval, and also the other needs during processes of developing products. It greatly shortens the testing cycle and reduces the risk of product developing investment, thus greatly enhancing the competitiveness of customers.Our factory has large and medium-sized vacuum machines. PS: only apply to plasic parts or rubber parts!
