Electronic & 3C Injection Molded Parts

 

 

Target Application Scope: Custom Electronic Enclosures, Thin-Wall IoT Device Housings, Precision Structural Brackets, and Connector Inserts.

 

 
 
Overview

 

OEM/ODM custom plastic injection molded parts for electronics demand strict dimensional stability, consistent wall thickness, and compliance with rigorous safety and environmental standards.


We provide end-to-end custom manufacturing services-ranging from DFM analysis and mold flow simulation to multi-cavity tool building, automated injection molding, and secondary processing. Operating with precision electric and servo-driven presses from 50T to 350T, we process engineering thermoplastics specified for impact resistance, thermal stability, and precise cosmetic finishes. Every production batch aligns with ISO 9001 quality management systems and complies with RoHS, REACH, and UL94 flammability requirements.

Manufacturing Capabilities

Manufacturing complex 3C injection molded components requires precise process control to eliminate warp, sink marks, and flash on intricate geometries.

Mold Design & Tooling:

In-house tooling fabrication utilizing CNC machining ( mm accuracy), high-speed EDM, and wire EDM. Mold flow analysis (Moldex3D) is standard for gate location optimization and warpage prediction.

Precision Molding Equipment:

25 servo-electric injection molding machines featuring clamping forces from 50T to 350T and shot weights from 10g to 800g, ensuring shot-to-shot dimensional consistency.

Secondary Operations:

Ultrasonic welding, heat staking, laser etching, pad printing, and automated EMI shielding coating (conductive paint / vacuum metallization).

Cleanroom Environment:

Class 100,000 cleanroom setup available for dust-sensitive optical and electronic assembly.

 

Applications
Plastic Support Components For Electronic Connectors

Smart Home Hardware:

Gateway housings, voice assistant shells, smart lock frames, and sensor mounting brackets requiring exact snap-fit assembly.

Electronic Module Positioning Components

Computer & Peripheral Accessories:

Hub enclosures, adapter frames, mouse shells, and internal structural spacers.

 

Electronic Device Internal Brackets

Wearable & Portable Devices:

Compact structural chassis and waterproof enclosures requiring thin-wall integrity (0.6 mm to 0.8 mm).

PCB Plastic Support Components

Telecommunications Equipment:

Router chassis, switch faceplates, and interface connector blocks built with high-specification flame-retardant resins.

 

 
 
OEM / ODM Services

We support full project lifecycles from initial concept design to volume production: 

01.

DFM & Engineering Support:

 

Direct engineer-to-engineer review of 3D CAD files (STEP/IGES) within 24 hours. We evaluate draft angles, gate locations, wall thickness uniformity, and sink mark risks prior to tooling fabrication.

02.

Rapid Tooling & Prototype Sampling:

Aluminum or P20 steel prototype molds delivered in 10 to 15 days for functional testing and assembly validation.

03.

Production Tooling:

 

H13, S130, or NAK80 hardened steel tooling guaranteed for 300,000 to 1,000,000+ cycles with structured maintenance logs.

04.

Supply Chain Flexibility:

 

Scalable batch production accommodating low-volume pilot runs (500 units) to high-volume automated manufacturing (100,000+ units/month).

 

Quality Control & Metrology

Quality assurance is integrated into every stage of tool building and production:


Incoming Raw Material Control:

Melt Flow Index (MFI) testing, moisture content analysis, and density verification for all engineering resins (SABIC, Covestro, DuPont, LG).


In-Process Quality Control (IPQC):

First Article Inspection (FAI) reports generated using 3D optical projection and CMM. Automated cycle-time monitoring and cavity pressure sensors ensure stable repeatability.

Dimensional Inspection:

Key functional dimensions, wall thicknesses, and geometric tolerancing (GD&T) verified via Hexagon CMM and Keyence optical comparators.

Functional Testing:

Drop testing, insertion force testing for connectors, thermal aging, and color spectrophotometer verification against Pantone/RAL standards ().

Documentation & Compliance:

ISO 9001:2015 certified facility; full material traceability with CoC (Certificate of Compliance), RoHS, and REACH documentation per shipment.

 

 

FAQ

 

 

Q: What are your typical lead times for tooling and mass production?

A: Standard production tooling fabrication takes 20 to 30 days depending on part complexity and cavity count. Prototype tooling takes 10 to 15 days. Once T1 samples are approved, mass production lead time is typically 10 to 15 days.

Q: How do you handle thin-wall warpage for large 3C electronic enclosures?

A: We run Moldex3D simulation prior to steel cutting to optimize gate locations and cooling channel layouts. During production, we use servo-electric injection machines with closed-loop pressure control and dedicated mold temperature controllers to neutralize internal stress.

Q: Can you match exact corporate brand colors (Pantone or RAL)?

A: Yes. We partner with certified masterbatch suppliers and execute color spectrophotometer readings under standardized D65 lighting to ensure strict batch-to-batch color consistency.

Q: What file formats do you require for an accurate quotation?

A: 3D CAD files in STEP, IGES, or XT format, alongside a 2D technical drawing specifying critical functional tolerances, surface finishes (SPI/VDI standards), resin grade, and anticipated annual volume.
