Engineered Core Value: Precision & Efficiency for NEV Connectors
Multi-Cavity Expertise
Our core specialization lies in designing and building high-yield multi-cavity molds (e.g., 4.8, 16, 32, 64+ cavities) specifically optimized for the intricate geometries and tight tolerances (±0.02mm typical) of automotive electrical connectors. This maximizes production efficiency and cost-per-part for high-volume NEV programs.
01
Dual-Shot Mastery
We excel in complex overmolding and insert molding processes critical for NEV connectors. This includes precisely encapsulating metal terminals (insert molding) or applying secondary seals/grips (overmolding) within a single, efficient cycle, ensuring perfect material bonding and dimensional integrity essential for electrical performance and environmental sealing.
02
Material Science Application
We design molds specifically for the high-temperature engineering thermoplastics demanded by NEV applications: PA66 GF30, PA6 GF25, PA9T, LCP, ABS, PPS GF30, ensuring optimal flow, cooling, and part ejection.
03
Robust, High-Longevity Build
Utilizing premium mold steels (SKD61, Viking, P20, SKH51) and adhering to international standards (Meusburger, Hasco, Misumi, DME), our molds are built for 1 to 2 million cycles, minimizing downtime and total cost of ownership. Structures are optimized as 2-plate or 3-plate molds with modular components for easier maintenance and future modifications.
04
Advanced Gating & Runner Systems
We select the optimal gating solution (submarine, cashew, pinpoint gate) and implement hot runner or cold runner systems based on material behavior, part design, and cycle time requirements to minimize waste and ensure consistent part quality.

Precision-Crafted Process: Your Custom Mold Development Journey
We don't just build molds; we partner with you through a comprehensive, risk-mitigated development process led by our seasoned engineers:
DFM & Feasibility (Your Blueprint, Our Insight): Submit your 2D/3D part drawings. Our engineers conduct a thorough Design for Manufacturability (DFM) analysis, evaluating material suitability, moldability, potential sink marks, warpage, and suggesting optimizations for cost and performance. We provide actionable feedback early.
Mold Flow Simulation (Virtual Perfection): Using advanced software, we perform detailed mold flow analysis (MFA). This predicts filling patterns, pressure drops, cooling efficiency, and potential defects (weld lines, air traps, shrinkage variations) before steel is cut, allowing for proactive design corrections and optimal gate/cooling layout.
Precision 3D/2D Mold Design: Leveraging MFA results and DFM feedback, our design team creates meticulous 3D and 2D mold designs. We specify materials, surface treatments, and standard components based on your requirements and our expertise in longevity and performance.
High-Precision Machining & Assembly: Utilizing our state-of-the-art workshop:
● EDM (6 units): Sodick AD32LS, Makino EDG2/EDG3 for intricate details.
● Wire-Cut EDM (7 units): Sodick AQ360LS, Seibu M50B for precision cores/cavities.
● Grinding (10+ units): Yutong 618S surface/CNC grinders for critical fits and finishes.
● Components are assembled with micron-level precision under strict protocols.
First Article Inspection & Sampling (FAI): Initial parts undergo rigorous inspection using our metrology lab:
● CMM (1 unit): Hexagon CMM Inspector for comprehensive 3D dimensional analysis.
● Projectors (3 units): Nikon Projector for profile checks.
● Nikon Altimeters (8 units): Dimension for depth with 0.001mm tolerance.
● Vision Systems (4 units): Wanhao 2D for fast GD&T verification.
● Full dimensional reports (FAIR) are generated against your specifications.
Scientific Molding & Process Validation: Our molding technicians utilize scientific molding principles on our 35 presses (Fanuc 30T-300T, Haitian 300T, Nissei 50T-80T verticals) to establish a robust, documented process window (PPAP documentation support available).
Pilot Run & Ramp-Up: Controlled pilot runs verify process stability and part quality before seamless transition to high-volume production within our facility.
