Manufacturing Capabilities
Production capability centers on high-precision injection molding machinery and integrated secondary operations.
Molding Equipment:
Horizontal toggle and hydraulic injection presses ranging from 160 t to 1,200 t clamping force, equipped with servo-driven take-out robots, centralized resin drying systems, and real-time cavity pressure monitoring.
Tooling Construction:
In-house tool room featuring high-speed CNC machining centers, wire EDM, and mirror EDM. Mold flow analysis (Moldflow) is standard during the DFM phase to predict warpage, weld lines, sink marks, and fiber orientation in glass-filled resins.
Secondary Operations:
Ultrasonic welding, heat staking, automated pad printing, and sub-assembly integration to reduce downstream supply chain steps.
Applications
01
Cabin Interiors:
Dashboard structural skeletons, instrument cluster bezels, seat adjustment bezels, and overhead console housings requiring precise fitment and low volatile organic compound (VOC) emissions.
02
Powertrain & Engine Compartment:
Under-hood brackets, sensor brackets, and fluid management covers subjected to continuous thermal cycling, structural vibration, and automotive fluid exposure.
03
Exterior Body & Chassis:
Fastener clips, trim retainers, and aerodynamic shielding components requiring high tensile strength, fatigue resistance, and environmental weathering stability.
OEM / ODM Services
Engineering and contract manufacturing support spans from initial prototype tool validation to serial mass production.
DFM (Design for Manufacturing):
Engineering review of 3D CAD models (STEP, IGES, CATIA) focusing on draft angles, uniform wall thickness, gate location optimization, and ejector pin placement.
Prototyping:
Rapid CNC machining of engineering plastics or 3D-printed master patterns for low-volume functional testing prior to production tooling investment.
Tooling Management:
Full customer ownership of tooling assets, transparent shot-counter tracking, scheduled preventative maintenance, and secure tool storage.
Quality Control
Strict quality verification protocols and compliance testing are integrated into every production phase.
Dimensional Inspection:
CMM (Coordinate Measuring Machine) verification, optical non-contact scanning, and custom go/no-go gauges for critical functional dimensions.
Material & Environmental Testing:
Melt flow index (MFI), density, ash content testing for glass-filled resins, and rigorous verification of RoHS, REACH, and strict interior VOC/odor emission standards.
Process Control:
Closed-loop machine monitoring tracking injection pressure, melt temperature, packing profile, and cycle time consistency.
Documentation:
Full PPAP Level 3 documentation packages, dimensional measurement results (PSW), material certificates of analysis (CoA), and IMDS submission prior to production release.
