Injection mold components custom machining

High-Precision Metal Stamping Dies and Injection Molding Solutions from Dongguan Haochen

Dongguan Haochen Precision Industry Co., Ltd. delivers world-class precision mold manufacturing services tailored for global industries such as automotive, electronics, medical devices, and consumer goods. With over 19 years of specialized experience in die-making and injection molding, we combine advanced technology, strict quality control, and engineering excellence to produce molds that meet or exceed international standards—including German DIN specifications. Our facility in Chang'an, Dongguan—a renowned hub for mold production in China—serves as the foundation for delivering consistent, high-performance results across every project.

Our core offerings include custom metal stamping dies, precision plastic injection molds, electroplating solutions, and automated tooling systems designed for complex industrial applications. Whether you need IC lead frames, LED terminals, optocoupler connectors, FPC terminals, or non-standard mechanical components, our team ensures exact replication of your design with exceptional dimensional accuracy and durability. By leveraging imported high-speed punching machines, CNC machining centers, and state-of-the-art testing equipment, we maintain a tolerance level of ±0.001mm for finished parts and ±0.002mm for mold dimensions—ensuring reliable performance even under heavy production loads.

• Ultra-Fine Tolerance Control: Achieve precision down to 0.001mm, ideal for micro-components in electronics and medical devices.
• Extended Mold Lifespan: Designed for up to 500,000 cycles without deformation—reducing downtime and maintenance costs.
• Top-Tier Materials: Use of premium steels like Sweden ASSAB and Japan Datong, paired with trusted mold bases from Longji and Fudeba.
• End-to-End Manufacturing: From initial concept design through prototyping, tooling, stamping, and surface finishing (including electroplating).
• Compliance & Standards: All processes adhere strictly to DIN standards, ensuring compatibility with global supply chains.

What sets us apart is not just our technical capabilities but also our deep understanding of industry-specific challenges. For example, in the electronics sector, we specialize in producing fine-pitch terminals for PCBs and connectors used in smartphones, wearables, and IoT devices. In automotive applications, our stamping dies support high-volume production of structural brackets, sensors, and fasteners with minimal scrap rates. Similarly, in medical device manufacturing, our molds are engineered for biocompatible materials, offering sterile-ready surfaces and precise geometries required by regulatory bodies like ISO 13485.

We serve clients worldwide who demand consistency, reliability, and innovation—not just in component quality but in delivery timelines and cost efficiency. Our one-stop approach includes fixture development, automation integration, and value-added finishing techniques such as zinc plating, nickel coating, and passivation treatments. This comprehensive strategy allows manufacturers to streamline their operations while maintaining superior product integrity.

Customers frequently praise our attention to detail, responsiveness during the prototyping phase, and ability to scale production rapidly without compromising on tolerances. Many have reported significant reductions in defect rates after switching to our molds, especially when transitioning from low-cost suppliers who prioritize volume over precision. One client in the European automotive sector noted how our dies reduced tool changeover time by 40%, directly impacting line throughput and reducing operational overheads.

Common questions often revolve around material selection for specific environments (e.g., corrosion resistance in marine electronics), lead times for custom molds (typically 2–6 weeks depending on complexity), and compliance with RoHS or REACH regulations. We provide full documentation for traceability and can offer rapid turnaround on urgent orders using our in-house inventory of pre-approved tool steel grades and standardized mold frames. Additionally, our engineers collaborate closely with clients during early-stage design reviews to optimize manufacturability, reduce tool wear, and enhance part functionality—all critical factors in competitive global markets.
