This service provides collaborative development and manufacturing solutions for plastic housing injection molds and silicone accessories for consumer electronics products. The core is to solve the problems of precision fit, multi-material bonding and integrated user experience between the high-gloss/fine-textured plastic shell and the soft sealed/cushioned silicone parts. Such products (such as smart speakers, wearable devices, home tools) require casings with structural strength, electromagnetic shielding (EMI) and aesthetic quality, while silicone parts need to provide a comfortable touch, reliable waterproof sealing (up to IP67) or shock absorption function.
JinYi Mold provides closed-loop services from design, rapid prototyping to mass production by integrating engineering experience in Consumer electronics housing injection mold and silicone casting for toys and household products. Using 3D printing and silicone mold casting for consumer products technology, we can complete design verification within 1-2 weeks, significantly shortening the development cycle and ensuring rapid product launch.

The mold is made of S136 or NAK80 mirror steel, and the pouring system is optimized through mold flow analysis (Moldflow) to ensure that warpage is controlled when forming thin-walled (up to 1.0mm) structures, and to achieve high-gloss (Ra < 0.02μm) or finely etched (VDI 3400 standard) surfaces. Commonly used materials are ABS (impact strength ≥20 kJ/m²), PC (light transmittance up to 88%) and PC/ABS alloy.
Liquid silicone (LSR) is used for silicone casting for toys and household products, providing Shore A 10-80 adjustable hardness range, as well as transparent, colored and other options. The silicone mold is copied from the 3D printing master mold to quickly produce flexible silicone rubber for consumer goods prototypes for assembly, touch and sealing testing.
Reserve buckles, grooves or chemical bonding areas during the structural design stage to ensure that the plastic shell and silicone accessories for consumer goods are firmly combined to avoid falling off after long-term use.
Use all-electric injection molding machines for a clean, precise production environment. For transparent or light-colored parts, strictly control the temperature of the barrel and mold to prevent yellowing.
Use vacuum injection molding process to eliminate internal bubbles in silicone parts. For parts that need to be combined with plastic in the mold, a two-color (hard plastic package soft plastic) injection molding or inlay injection molding process is used.
Provides various surface solutions such as spraying (UV paint, rubber paint), vacuum coating (PVD), IML in-film transfer, etc.
Apply anti-fingerprint (AF) coating, anti-scratch (Hard Coating) coating or electromagnetic shielding coating to the plastic shell. Plasma treatment of silicone parts to improve adhesion to inks or adhesives.

We have established a fast-paced verification process for consumer electronics products.
The functional prototype produced by 3D printing and silicone mold casting for consumer products can be subjected to drop test (such as 1.2 meters height, multiple angles), key life test (≥100,000 times), waterproof test (IPX7) and preliminary wear resistance test.
Injection molds undergo T0-T2 mold trials, and mass-produced plastic parts are inspected for size (CMM), color difference (ΔE<1.5), and material (flame-retardant UL94). Silicone parts are tested for hardness, tensile strength and long-term aging.
All materials comply with RoHS and REACH standards, and children's product-related parts can meet specific regulatory requirements such as EN71 and FDA.
JinYi Mold supports everything from small batch trial production of dozens of pieces to large-scale mass production of millions of pieces. With our supply chain integration capabilities in the field of Consumer electronics housing injection mold and silicone accessories for consumer goods, we are able to ensure stable quality, competitive costs and on-time delivery.
