Vacuum Casting processing services for prototype Custom
Silicone replication (also known as vacuum casting) is a technology that uses silicone molds, and Yigu is an expert in this field. This technology is an economic alternative to small-scale production of plastic components.
What is vacuum casting prototype?
Silicone replication is an economical and efficient alternative solution for small-scale plastic parts production, which can accurately replicate the final molded parts or finished products. Usually, we use silicone rubber to make molds and combine them with CNC or SLA parts as master molds.
These molds are capable of replicating all the structural and surface features of a product, and the overmolding can be used to replicate another product. A set of silicone molds can usually replicate 10-15 sets of products.
Silicone replication production process
Model making
Based on your 3D drawings, we will use CNC machining and 3D printing (SLS/SLA) technology to produce the main parts. For parts with complex shapes and structures, we will also consider using SLA technology to make molds.
Silicone mold production
We will inject silicone around the mold and then use a vacuum process to remove all air. Próximo, place the mold in a 40 ℃ oven for curing. The curing time will depend on the volume of the mold and generally takes 8-16 horas.
Vacuum film coating
We pour the resin into the mold in the vacuum chamber through computer control, and then put it back into the oven for curing. In general, the curing time for small components is 1-3 horas, while large components require 3-6 horas. Después de curar, we will remove the cast parts from the silicone mold and prepare for the next cycle.

Silicone Mold Duplication Technology Guide
Standard accuracy: The standard tolerance is ±0.15 mm/100 mm, with a maximum accuracy of ±0.05 mm.
Maximum part size: The vacuum equipment can accommodate mold specifications of 1.8 m × 1.2 m × 1.0 m.
Minimum wall thickness: The minimum wall thickness is 0.5 mm, and the recommended thickness is between 1.5 mm and 2.5 mm.
Standard delivery time: Arriba a 50 pieces can be produced within 7 a 10 días, depending on part specifications and quantity.
Service life of silicone molds: Each mold can produce up to 20 piñones, but if the parts have high requirements, such as clear or complex structures, then one mold can only produce 12 or even 10 piñones.
Surface finish and other functions: Coloring, texturing, cuadro, coating, transparent polishing, embedding, and over-molding.
