As a professional Chinese silicone casting manufacturer, JinYi Mold is committed to providing the most efficient customized silicone solutions for the medical, automotive and high-end consumer electronics industries. We are well aware of the strict standards for material safety, production cleanliness and regulatory compliance in the medical and device fields. Our core advantage lies in the use of high-precision silicone molds and vacuum casting technology to provide one-stop services from rapid prototyping (Fast Turnaround) to small and medium-sized batch production for medical seals, gaskets and surgical instrument components, thereby meeting customers' dual needs for speed and quality during the R&D iteration and market introduction stages.
We have an engineering team of more than 500 people and an ISO 9001 quality system, and have successfully expanded our engineering control experience in precision injection molds to the silicone field. With our independent mold design and processing capabilities, we ensure that the entire process from medical grade material selection, mold flow channel optimization to clean room production can be controlled, focusing on solving key issues in core areas such as small size, complex geometric structure, biocompatibility and sealing performance of silicone parts.

For medical seals and surgical instrument components, our first choice is platinum-vulcanized medical-grade silicone certified to ISO 10993 and USP Class VI to ensure biocompatibility and long-term stability. Our material library includes many types of special silicone such as high tear resistance, transparency, and high temperature resistance. We can provide professional material selection suggestions based on the functional requirements of customized silicone parts (such as flexibility, conductivity, and flame retardancy).
We use high-precision silicone molds with cavity accuracy as high as ±0.05mm to ensure strict consistency in component dimensions and microscopic surface quality. Combined with fast-turnaround silicone mold casting services, we can complete the delivery of prototypes or small batches of products within days, greatly accelerating customers' R&D verification and clinical testing processes.
Once casting is complete, we offer a full range of value-added process services, including sandblasting, laser engraving, silk screen printing to meet specific tactile or marking needs, as well as cleanroom packaging and sterilization validation support to comply with sterile barrier requirements. All operations strictly comply with medical product production specifications.

We strictly abide by the quality management system related to medical devices to ensure that each batch of products is traceable and has stable and reliable performance.
We strictly monitor and record key parameters such as vacuum degree, mixing ratio, solidification temperature and time of vacuum casting to ensure the stability of the process.
In addition to routine dimensional inspection (using optical projector or CMM) and full appearance inspection, we also provide material certification reports, chemical performance tests, and basic sealing function tests based on customer needs.
We can provide production record documents that comply with quality system requirements for silicone parts for medical purposes, helping customers complete their own product registration and marketing applications.

We understand the differentiated needs for packaging in different industries. For medical seals and surgical instrument components, we provide vacuum bagging, blister box packaging and other solutions that meet cleanliness requirements; for other industrial components, we use scratch-resistant customized packaging. As a manufacturer based in China, we rely on our efficient local supply chain and logistics network to ensure fast and reliable global delivery.
