We combine advanced 5-axis CNC machining and precision grinding technology to produce high-durability mold components from hardened H13 and SKD61 mold steel. This complete mold part set includes ejector pins, core inserts, discs and covers, engineered specifically for high-volume TWS earphone injection molding production. With ultra-tight tolerances ranging from ±0.002mm to ±0.005mm, our mold parts deliver flawless cavity fit and smooth ejection performance, solving common mass production pain points such as high wear, frequent part replacement and elevated defect rates.

Dawang Precision specializes in custom mold parts for Bluetooth earphone injection molds. This precision component set includes ejector pins, core pins, inserts, and covers machined from hardened mold steel—delivering exceptional wear resistance, dimensional accuracy, and long service life for high-volume TWS earbud production.

Features & Benefits

Million-Cycle Durability with Hardened Mold Steel

Our precision injection mold ejector pins and core components are manufactured from premium H13 and SKD61 mold steel, with specialized heat treatment for exceptional hardness and wear resistance. This hardened steel construction delivers reliable performance for over a million injection molding cycles, drastically reducing mold downtime, part replacement frequency and long-term production costs for manufacturing enterprises.

Ultra-Precision Tolerance for Flawless Mold Performance

Every custom TWS earbud mold insert is machined to ultra-tight tolerances of ±0.002mm to ±0.005mm, verified by industry-leading Zeiss CMM inspection equipment with 0.002mm measurement accuracy. This mold-grade precision ensures a perfect fit with your existing injection mold cavity, enabling smooth, consistent ejection of TWS earbud components and minimizing plastic part defects, scrap rates and rework requirements for high-volume production.

Advanced Surface Treatment for Extended Service Life

We offer two premium surface finish options for our hardened steel mold pins: mirror polish and chrome plating. Both treatments deliver exceptional anti-wear and corrosion resistance, reducing friction during the ejection process and preventing plastic residue buildup on component surfaces. This not only extends the service life of the mold parts, but also improves the surface quality of finished plastic earbud components, ensuring consistent product quality for every production batch.

Full Customization & Rapid Production Support

Every set of consumer electronics mold components we produce is fully tailored to your Bluetooth earphone mold cavity design and production requirements. We accept custom drawings, samples and design specifications, with a free detailed quote provided within 24 hours. Our rapid prototyping service delivers custom sample parts in 7-10 days, with flexible production capacity to support both small-batch prototyping and high-volume mass production for our business partners.
