Custom Silicone Molding- Choose the right company for it
Silicone prototypes are customized using different modes like solidity, move, and injection molding. The unique molding method is chosen depending on the silicone product geometry, the application needed, and the type of silicone material. Choosing the right silicone molding process is important as it affects the silicone product quality, method effectiveness, and primary equipment costs. Thus, you can speak to a reliable and reputable custom silicone mold production company that can showcase the silicone molding progression to verify their effective methods to get the best results for your requirement.
Different techniques involved in custom silicone molds production:
Compression: Compression can be accomplished for good silicone fraction geometry. HCR silicone fabric is put and weighed on a hot mold top. The mold is then compressed, and the fabric starts curing the desired shape.
Transfer: A transfer is an ideal alternative when the silicone design is complicated and includes a complex center. The fabric is put on hold and compressed. Once compressed, it flows through a runner and opens in the element shape.
Injection: if you need high-volume production or medical-level silicone products, you need an effective technique. The liquid rubber silicone is put in injection barrels and injected into the mold at extreme pressures.
Part design for silicone molding
It is stated that major part design is achieved when thermoplastic injection molding is done for the silicone design part. Even when silicone doesn’t sink or wrap as thermoplastics, regular wall thickness is needed for the silicone injection mold. It lets continuous silicone fabric for liquid injection mold method.
Silicone lets the design benefit from planning with severe undercuts as the material can distort in any way and can relieve and expand accordingly with the help of geometry tooling.
Liquid silicone overmolding is done according to the requirement and can be injected using a mold to get longevity. It is important to choose the most suitable technique for machining, considering the mold complexity and silicone part. There are several influencing aspects such as project timeline, budget and confidence of the designer, and the selection of the right molding technique and mold material.
Silicone overmolding is the only way to bond a part with silicone material. So, when you talk about liquid silicone overmolding bonding, you should keep two things in mind- silicone adhesion to the surface for molding and the temperature needed for silicone curing.
Some essential points to know when doing silicone over-molding:
- Silicone overmolding to silicone is a simple process if silicone bonds with silicone efficiently.
- The strength of overmold bonding enhances with time.
- Using bonding improvised silicones and primers can enhance chemical bonding.
- Polymers include nylon, resin, and polycarbonate, the best selection for the overmolding procedure.
- To get clean silicone overmolding, you should ensure that the parts have the required tight tolerance. To produce a clean overmold object, you need a balanced dimension part.
