Product Range & Typical Geometries
We mold a broad spectrum of functional components tailored to specific mechanical and environmental requirements:
Housings & Enclosures:
Electronic device shells, sensor bodies, industrial control boxes with integrated snap-fits and threaded inserts.
01
Mechanical Drives & Gears:
Spur gears, worm gears, cams, and low-friction bushings requiring high wear resistance.
02
Connectors & Housings:
High-pin-count electronic connectors, terminal blocks, and insulating spacers with thin-wall sections (< 0.5 mm).
03
Fluid & Pneumatic Components:
Valve bodies, manifolds, fittings, and impellers requiring leak-free sealing faces and chemical compatibility.
04
Overmolded & Insert Parts:
Metal-plastic hybrid components (brass inserts, stamped metal terminals) and soft-touch grips (TPE/TPU over rigid substrates).
05
Manufacturing Capabilities & Engineering Support
Manufacturing performance relies on process control, thermal management, and precise machine parameters:
DFM & Mold Flow Analysis:
Every project undergoes automated and engineer-led DFM review before tooling begins. We analyze gate locations, weld lines, sink marks, draft angles, and volumetric shrinkage to prevent shop-floor defects.
Tooling Construction:
In-house tool room equipped with CNC machining, Wire EDM, Sink EDM, and high-speed milling. Tool steel grades include P20, H13, NAK80, and S136 based on expected life cycles and abrasive fillers.
Process Control:
Closed-loop injection molding machines with real-time monitoring of cavity pressure, melt temperature, injection speed, and cooling cycles to ensure batch-to-batch repeatability.
Secondary Operations:
Ultrasonic welding, laser marking, pad printing, heat staking, and custom sub-assembly.

OEM / ODM Partnership
Build-to-Print (OEM):
Production executed strictly to your finalized STEP/IGES files and 2D drawings featuring GD&T callouts, material specifications, and surface finish requirements (SPI A2 to D3).
Engineering Collaboration (ODM):
Support from initial concept stage through prototyping, material selection, mold design optimization, and mass production scaling.
IP Protection:
Strict Non-Disclosure Agreements (NDAs) enforced across all engineering and manufacturing stages.
Quality Control & Inspection
Quality is verified through measurable physical and dimensional data rather than visual inspection alone:
Incoming Material:
Verification of raw resin pellets via Melt Flow Index (MFI) testing and Certificate of Analysis (CoA) review from primary suppliers (Sabic, DuPont, Covestro, BASF).
In-Process Inspection:
First Article Inspection (FAI) reports generated for initial shot approval. Regular dimensional audits during production runs based on AQL sampling standards.
Metrology Equipment:
Coordinate Measuring Machines (CMM), optical video measuring systems, digital height gauges, and tensile strength testers.
Traceability:
Lot traceability maintained from raw material batch number through molding shift logs to final shipment packaging.
