A One-Stop Manufacturing Base for Optical Module Housings Pinjack Optronics Tamsui Headquarters serves as the main production base for optical module housings, integrating key processes such as engineering evaluation, molding, surface treatment, and quality inspection.
With our in-house team and well-equipped facilities, we provide one-stop services from design drawing evaluation to mass production delivery, helping customers shorten development timelines and ensure stable product quality.

Processes and Departments Product Feasibility Assessment & Mold Design Upon receiving customer drawings and requirements, our engineers conduct structural and process evaluations and work closely with mold makers to assess feasibility. Simultaneously, we communicate with customers to ensure the design meets production conditions and customization needs.

Die-Casting & Plastic Injection Molding The Tamsui headquarters is equipped with metal die-casting and plastic injection production lines, precisely controlling dimensions and appearance quality. We produce high-precision housings and plastic components that meet the demanding standards of the optoelectronics industry.

Deburring Standardized deburring processes remove burrs from metal parts, creating smooth surfaces, improving safety, and enhancing the quality of subsequent surface treatments.

Sandblasting Professional sandblasting equipment is used to evenly treat material surfaces, improving product texture and consistency, and providing a solid foundation for subsequent plating or finished appearance.

In-House Plating Facility Pin Jie Optoelectronics owns a fully automated plating plant in Wuku District, New Taipei City. Barcodes are used to set plating recipes, ensuring consistent quality while optimizing lead times and cost efficiency.

Quality Assurance & Control (QA/QC) Complete quality inspection processes and equipment, including temperature- and humidity-controlled chambers and coordinate measuring machines (CMM), ensure thorough checks from production to shipment, guaranteeing that products meet customer specifications and quality standards.

One-Stop Manufacturing Service

From initial evaluation, molding, surface treatment, to quality inspection, Pin Jie Optoelectronics provides fully integrated manufacturing services. Customers only need to provide design drawings, and we handle the evaluation and production with confidence.
