This product line focuses on providing high-performance liquid silicone (LSR) components and overmolding solutions for the automotive industry, which are widely used in seals, shock absorbers, buttons, wire harness protective covers and interior integrated components. Automotive silicone parts need to maintain stable sealing, elasticity and durability in a wide temperature range of -40°C to 200°C, long-term contact with engine oil and high vibration environments. JinYi Mold relies on the strict standards accumulated in the field of medical-grade silicone casting and has successfully applied the purity control, precision molding and traceability management system in manufacturing biocompatible silicone parts to the production of automotive-grade silicone parts, achieving high-quality delivery from rapid design verification to stable mass production.
We know that automotive electronics and intelligence have higher requirements for component integration and reliability. As a manufacturer with deep experience in both the automotive and medical fields, we focus on solving key engineering problems such as strong bonding between silicone and various substrates (such as PA, PC, metal), uniform filling of complex thin-walled structures, and meeting long-term service life requirements. We provide customers with full-process services covering material selection, mold design, and automated production.
Key points of systematic engineering technology
Rapid iteration and design verification:
We use silicone mold rapid prototyping technology and create functional prototypes within a few days based on the customer's 3D data. This technology is used to evaluate the assembly fit and feel of automotive parts. Its efficient iteration capabilities also benefit from our extensive experience in the field of silicone overmolding prototype development for medical devices, ensuring that design problems can be discovered and corrected early, thereby significantly shortening the development cycle.
Material science and precision overmolding:
Liquid silicone overmolding (LSR Overmolding) is one of our core technologies. By optimizing the pretreatment process, accurately controlling the mold temperature, and using an efficient adhesive system, we ensure that the LSR and the base material are inseparable and realize dual-material integrated components. The LSR material used meets automotive industry specifications, its performance has passed strict testing, and it can provide high-purity grade options close to medical-grade silicone to meet high-end needs such as in-car air quality.
Automated production and high-performance molds:
We specially design and manufacture special molds for LSR, equipped with needle valve hot runners, vacuum exhaust devices and efficient cooling systems to cope with the rapid solidification characteristics of silicone. The production line has a high degree of automation, using robots to realize automatic pickup and online visual inspection to ensure the stability and consistency of the production process. This strict standard comes from the cleanliness control philosophy we always adhere to when producing biocompatible silicone parts.
Validation and Quality Assurance
We implement the stringent validation procedures common in the automotive industry and infuse them with the reliable quality concepts found in medical device production.
Process and bonding strength verification:
The parameters of the overmolding process are optimized and locked, and the silicone-substrate bonding interface is tested for tensile shear strength and peeling test after hot and cold cycles to ensure its lifetime reliability.
Comprehensive environmental and durability testing:
Components must pass a full set of evaluations including high temperature aging resistance, oil/chemical resistance, compression permanent deformation test, high and low temperature alternating and vibration fatigue testing to simulate the use conditions during the vehicle life cycle.
Material and process traceability:
We have established a full-process traceability system from LSR raw material batches to molded products, and can provide volatile organic compound (VOC) test reports of materials to meet the environmental protection requirements of high-end OEMs.
Delivery and support
We can meet all stages of needs from rapid prototyping of silicone molds, small batch trial production to large-scale automated production. Whether it is the sealing gasket of the new energy vehicle battery pack or the integrated silicone buttons in the smart cockpit, we can provide reliable solutions.
