This product line is carefully built by JinYi Mold, focusing on providing high-performance liquid silicone (LSR) injection molding solutions for the consumer electronics and automotive industries. With rich engineering experience accumulated in the field of flexible silicone casting for automotive parts, we apply stringent automotive-grade standards to the production of consumer electronic silicone accessories (such as smart wearable watch bands, earphone plugs, and protective cases) to ensure that the products reach excellent levels in terms of touch feel, durability, environmental tolerance, and precision assembly. The core mission is to solve the process challenges such as filling difficulties, bubble control and stable bonding faced by silicone materials during the molding process of high-precision, tiny thin-walled structures.
JinYi Mold has mature precision mold development capabilities and a professional engineering team of more than 500 people. We provide full-process services from material selection, mold design to mass production process verification. We are not only proficient in silicone casting for consumer products, but also delve deeper into silicone casting for automotive decorative parts with higher requirements (such as sealing strips, buttons, decorative covers) to ensure consistency, traceability and high quality throughout the entire process from concept to mass production.
Based on our in-depth understanding of high-performance automotive silicone component materials, we work with top material suppliers to carefully select the most suitable LSR materials for customers (hardness range covers Shore A 10-80). The mold uses high thermal conductivity steel and a full hot runner system, and has special exhaust and cold runner designs based on the rheological characteristics of silicone, aiming to achieve rapid and uniform solidification and effectively reduce internal stress.
Our molding process is capable of high dimensional accuracy of ±0.05 mm. In the field of consumer electronics, we integrate advanced processes such as multi-color/multi-material co-injection and in-mold inserts; while in the automotive field, we focus on meeting the performance requirements of long-term weather resistance, oil resistance and wide temperature (-40°C to 200°C). Post-processing processes, such as spraying (providing UV protection and color), in-mold/secondary vulcanization bonding, laser engraving and plasma treatment, are all completed in a strictly controlled clean environment.
In order to meet the requirements of the consumer electronics and automotive industries for product purity and consistency, we provide comprehensive automation solutions, including robot pickup, automated visual inspection and online weighing systems, to ensure the stability and efficiency of the production process and strictly comply with the cleanliness standards of relevant industries.
We follow the same rigorous quality verification process as precision injection molding to ensure that each batch of silicone accessories meets specifications.
Use DoE (Design of Experiments) method to optimize and lock key parameters such as injection speed, temperature, pressure and vulcanization time to ensure the stability and reliability of the process window.
In addition to conventional dimensional (CMM) and appearance inspections, products can also undergo a series of tests such as tensile strength, tear strength, abrasion resistance, long-term aging, chemical resistance and biocompatibility according to needs.
Silicone parts will be tested with corresponding electronic shells or automotive interior parts to verify the mold assembly feel, sealing performance and functional reliability after long-term use.
We deliver not only silicone products, but also proven manufacturing solutions. For consumer product silicone parts projects, we focus on rapid response and market timeliness; for automotive silicone parts, we provide a complete PPAP (Production Part Approval Process) document package, including process flow diagrams, control plans, material certification and performance test reports, to support the smooth mass production of customer projects.
JinYi Mold is committed to combining the rigorous engineering concepts of the automotive industry with the rapid innovation needs of the consumer electronics industry to provide customers with one-stop solutions for high-performance silicone parts from concept design to global supply chain delivery.
