Project Description

Silicone vacuum casting for prototype or 25+ short run production plastic parts

The silicone vacuum casting is also called urethane-casting. The silicone vacuum casting rapid manufacturing process is the perfect choice for prototyping and small batch production.JIGNXIN precision machinery Ltd, is a professional custom rapid manufacturing factory of silicone vacuum casting service producing the parts in a range of polyurethane (PU) resins and cast nylon. The parts made by vacuum casting is to replicate and replace engineering polymers for prototypes and low-volume production.  JINGXIN is always seeking to supply our best solution to industrial rapid manufacturing.

Application and Advantage:

Short lead times: Silicone Vacuum casting tooling will be finished within 3-5 days 

Low tooling cost: Liquid  Silicone is used to build the vacuum casting tooling. it is very low-cost than steel plastic injection mold.

End-use Application: Silicone Vacuum casting systems produce high-quality parts that closely replicate the performance attributes of injection moulded parts;

Speed to market: Best solutions for developing products, fast turnaround to change the RTV silicone mold to meet market demands in various industries including medical, consumer electronics, automotive.

Vacuum casting process details

vacuum casting master model

Master Model

The master model is usually produced via 3D printing or CNC machining from CAD model, however, if a direct copy of an object is required, then this object can be used to make the silicone rubber mould.

Vacuum casting silicone mold

RTV silicone rubber Mold making

Design the gate and Make a frame by rigid paper or ABS plate surround the master model, Pulling the special silicone into the frame, then put it into vacuum machine and oven.

vacuum casting mold parting line

Cutting silicone mold

Cut the silicone mold according to the designed parting line, take out of the master model.

ABS like material

Casting material, Plastic-like

Component A is a flowing liquid silicone, component B is a curing agent.Parts can be produced in one single material or multiple materials using co-molding or over-molding. Flexibility in casting materials include color, with or without texture, high impact strength, tear resistance, and high heat deflection.

Vacuum machine

Vacuum machine is used to keep the casting material in cavity without bob and full fill every corner

oven machine for vacuum casting

Oven machine

Put The mold into the oven baking 3-4 hours, so that the silicone mold to accelerate curing molding
