What Is Injection Molding?

Injection molding is a manufacturing process that melts plastic resin and injects it into a precision mold under high pressure.

After cooling, the mold opens to produce consistent plastic parts with complex shapes, fine details, and repeatable dimensions.

Our Service Advantage

TY-EMS supports plastic parts for electronic products from design review to production.

We help evaluate manufacturability, recommend suitable materials, check assembly fit, and provide finishing, inspection, and stable production support.

Answers to Your PCB Manufacturing Questions

Answers to your PCB manufacturing questions

How do you ensure product quality and reliability?

We support quality control through material inspection, process checks, functional testing, assembly inspection, and final packaging review. Testing items are confirmed based on each product and project requirement.

Yes. We support projects from early prototypes and engineering samples to pilot runs and batch production, helping customers verify design, assembly, testing, and production requirements before scaling up.

You can send Gerber files, BOMs, pick-and-place files, assembly drawings, product photos, samples, STEP/3D files, or basic project requirements. Our team will review the information and suggest the next steps.

We support PCB manufacturing, PCB assembly, component sourcing, testing, product enclosures, box-build assembly, packaging, and delivery coordination for electronic product projects.

Lead time depends on product complexity, component availability, tooling needs, testing requirements, and order quantity. We review each project and provide a suitable schedule based on confirmed requirements.

Yes. We can support custom electronic product projects based on your idea, drawings, BOM, samples, photos, or technical requirements, and help move the project from review and prototyping to production and delivery.
