High-efficiency technical production for single-material components with tight aesthetic requirements.

Precision encapsulation of metal threads, pins, and electronic sensors for high-strength mechanical bonding.

Permanent chemical adhesion of soft TPE/TPU resins over rigid substrates (PC, ABS, Nylon) for ergonomic and sealing applications.

Automated injection of two different resins for superior interface precision and reduced labor costs.

Our 3,000T press fleet specializes in components up to 15,000g (15kg) and 2,500mm in length. By utilizing Sequential Valve Gating (SVG), we meticulously manage the melt front to eliminate weld lines on large aesthetic surfaces—a critical Tier-1 requirement for automotive bumpers and exterior trims. We integrate gas-assist technology and high-efficiency cooling circuits to maintain uniform wall thickness and prevent sink marks in thick structural ribs, ensuring zero-warp performance in massive geometries.

We isolate fill, pack, and hold stages to find the most robust process window.

Real-time monitoring of rheology to eliminate batch-to-batch variation.

Data-driven methodology ensuring process stability CPK & PPK > 1.67 for critical OEM dimensions.

Precision starts in our toolroom. With 25 sets of high-speed 5-axis CNC centers, we machine complex mold architectures in a single setup, eliminating the cumulative errors of traditional 3-axis shops. We utilize premium steels including S136 and H13 (HRC 48-52) to build SPI Class 101 Molds, guaranteed for over 1,000,000 cycles. This internal control ensures that mold maintenance and engineering changes are executed with micron-level accuracy and minimal lead-time impact.

We process resins up to 420°C using bimetallic barrels specialized for abrasive and high-heat materials like Ultem and PPS. Jucheng ensures uniform fiber distribution and structural integrity across all complex component geometries, maintaining material properties even in high-glass-fiber reinforced polymers (up to 50% GF).

The challenge of overmolding lies in the molecular bond. Our engineers perform rigorous chemical compatibility analysis to ensure TPE/TPU materials bond permanently to rigid substrates without mechanical interlocks. In Insert Molding, we manage differential thermal expansion to prevent stress cracking in threaded inserts and connectors, ensuring long-term functional performance in extreme industrial environments.

Precision is verified, not assumed. Our metrology lab features automated CMM (±0.003mm precision), OGP scanners, and moisture analyzers. Every production batch is accompanied by a detailed FAI (First Article Inspection) report and SPC data analysis, providing absolute quality transparency before parts leave our facility.
