Product Description

OEM rapid prototyping silicone rubber mold vacuum casting polyurethane castings

 

 

What Is Vacuum Casting Or Urethane Casting?

 

Vacuum casting or urethane casting is a process that involves pouring urethane resin into a space between two silicone mold halves. Using a vacuum chamber to extract air from the mold during the vacuum casting technique helps guarantee that the object takes on the correct shape.

 

This vacuum casting technique is often used to make rubber and plastic items. Since urethane molding can be quicker and less expensive than other techniques like injection molding, it often finds use in prototyping projects or small-scale production runs. The procedure creates high-quality, bubble-free castings with a flawless, smoothly textured surface since it is done under vacuum.

 

Application and Advantage:

 

Short lead times

 

Silicone Vacuum casting tooling will be finished within 5-8 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.

 

 

There are some differences:

 

In injection molding, molten polymer is pushed into the mold cavity under high pressure and high temperature using a hopper and lead screw. Vacuum casting operates at low temperatures. Instead of molten plastic, it works with liquid resins that are drawn into the mold under a vacuum, much like the capillary action inside a plant stem. So while there are many different resins available to mimic various polymers, prototyping in the final injection-molded material is not possible.

 

After oven-curing, parts still undergo some post-curing for up to a week and remain vulnerable to UV radiation and high temperatures.

 

Because the mold is flexible, there are limits to part size and shape. Still, there are specific techniques to enable exceptions. For example, phased casting is the use of metal supports to counteract gravity for casting elongated parts in a three or four-part mold.

 

Vacuum casting handles variable wall thickness better than injection molding, because there is no heating-cooling cycle of the cast material. This results in less part distortion.

 

A silicone mold allows for significant undercuts in the part design. However, when testing for injection molding, it’s recommended to stick to the injection molded design as much as possible and build in the required draft angles of the final product.

 

Vacuum casting results in nearly zero waste, whereas in injection molding up to 20% of the used polymer is lost due to scrap rates, residues, and overproduction.

 

 

Vacuum Urethane Casting

 

In this step, the original master pattern is replicated through casting in a vacuum chamber. First, the mold is taped to a wooden board and vent straws plus a pouring funnel are added to it.

 

The two-component resin is measured and mixed with a coloring agent for pigmentation. Then, the casting material is degassed in a vacuum chamber for a few minutes.

 

The polyurethane blend is now ready for pouring. The riser straws will indicate when the cavity is completely filled up. After curing at 70˚C, the mold is opened to reveal a carbon copy of the original model with all details and surface textures preserved.

 

The finalization consists of trimming the edges of flash material, an extra polishing cycle with 1000-grit sandpaper, and oven-curing to improve

the part’s material properties.
