Custom Solutions for Precision Injection Molded Parts of Robot Arms: From Pain Point Resolution to Mass Production Empowerment
When a manufacturer of industrial robots developed collaborative robot arms, it encountered bottlenecks in the mass production of core injection molded parts: excessive tolerances of joint connectors caused operational jamming, insufficient wear resistance of harmonic reducer housings led to frequent abrasion, the trial production yield was only 76%, and the need to adapt to global supply chain mold standards forced a halt to mass production plans. As an injection mold factory covering 20 product categories including home appliances, medical devices, digital products, and connectors, we systematically addressed these technical challenges, achieving dual breakthroughs in part precision and mass production efficiency, and providing solid support for the customer’s strategic implementation.
I. In-depth Analysis of Core Problems
1. Precision Threshold Challenge: Core parts such as robot arm joint connectors and sensor housings require tolerances controlled within ±0.005mm, and traditional molds struggle to achieve micro-level dimensional stability; 2. Performance Adaptation Conflict: Joint parts need high-frequency load-bearing and wear resistance, while housings demand lightweight and impact resistance, making it difficult to match material selection with mold processes; 3. Multi-standard Compatibility Pain Point: The customer needs to simultaneously meetDEM, HASCO, MISUMI and Moldbao standards, with drawing formats including STEP and X_T, leading to potential errors in cross-standard conversion; 4. Delivery Efficiency Bottleneck: Long T1 testing cycles and poor connection between mold manufacturing and mass production fail to keep up with the rapid iteration needs of robot products.
II. Implementation of Customized Solutions
1. Mold Design and Standard Adaptation: 3D design software such as NX, CAD, and PROE are used for modeling, while SOLIDWORKS optimizes part structures. MOLDFLOW analysis is employed to predict weld lines and deformation risks, accurately optimizing gate layout and conformal cooling channels. Mold accessories strictly comply with multiple standards: guide pillars and ejector pins adopt HASCO specifications, positioning components use MISUMI standards, and Moldbao precision inserts ensure core accuracy. Drawings support seamless docking with customer systems in STEP and X_T formats.
2. Material and Process Upgrade: The mold for joint connectors is made of S136 stainless steel, which reaches a hardness of 58-62HRC after heat treatment and is coated with TiN to triple its wear resistance; the housing adopts reinforced PC/ABS alloy to balance lightweight and impact resistance; the harmonic reducer end cover uses POM material, with optimized injection pressure curves to avoid shrinkage deformation. Leveraging precision control experience from medical mold manufacturing, we maintain dimensional accuracy throughout the process.
3. Full-process Delivery Control: T1 testing is strictly completed within 3-5 days, with dimensional inspection reports and wear resistance test data provided simultaneously; the mold manufacturing cycle is 25-35 days, using ISPM15 standard wooden crates for packaging, with mold cavities vacuum-sealed after anti-rust treatment; delivery terms are FOB Shenzhen/Ningbo Port, accompanied by COA material certificates, RoHS and REACH compliance documents to support global supply chain adaptation.
