Our Comapny Profile

Yize Mould’s main business covers precision parts processing, injection mold design and manufacturing, cleanroom injection molding etc.

Steps for liquid silicone injection molding

For products requiring cleanroom injection molding, the steps include demand analysis and design confirmation, mold design and DFM (Design for Manufacturing) analysis, material selection and procurement, mold machining and manufacturing, mold assembly and debugging, mold trial and adjustment, mass production of injection molded products, as well as after-sales service and maintenance. These steps ensure that the injection-molded products meet customer requirements, are processed precisely, and optimized through mold trials, ultimately delivering high-quality, durable injection molded products that satisfy customer needs.

/01 Requirement Analysis and Design Communication

Requirement analysis and design communication are crucial steps in ensuring the success of customized mold opening and injection molding. Effective communication ensures that all parties involved in the project (clients, designers, engineers, mold manufacturers, etc.) have a clear and consistent understanding of the requirements and design plan.

/02 Mold Assembly and Debugging

Mold assembly and debugging are vital stages in the mold manufacturing process, directly determining the final usage effect and production efficiency of the mold. During this stage, various manufactured components are assembled into a complete mold, and through mold trials and debugging, it is ensured that the mold can operate smoothly and efficiently.

/03 Raw Material Mixing

Liquid silicone rubber is divided into two components, A and B, which are precisely mixed in a 1:1 ratio using an automatic proportioning mixing pump. Color masterbatches can be added to achieve color matching. The entire process is fully sealed and pollution-free, ensuring the cleanliness of the raw materials.

/04 Injection Molding

The mixed silicone rubber is injected into a high-temperature mold cavity (approximately 170–200℃) through a cold runner system. Liquid silicone rubber exhibits excellent flowability and self-demolding properties, making it suitable for producing precision, thin-walled, and complex structural parts.

/05 Curing and Demolding

After curing, the products are automatically demolded using mechanical ejection or pneumatic systems. Due to the non-stick properties of liquid silicone rubber, demolding is fast, and the product surface has a high degree of smoothness and gloss.

/06 Inspection and Packaging

The products are packaged in dust-free packaging to maintain cleanliness, making them suitable for use in medical, laboratory, infant and child care, wearable device, and other fields.
