Plastic Injection Molding Services—Precision Manufacturing for Regulated Industries

Plastic injection molding remains one of the most efficient and scalable ways to manufacture high-quality components for medical, biotech, and diagnostic products. At Ciro Manufacturing, our plastic injection molding services are built around precision, repeatability, and compliance—with every tool, material, and process engineered to meet the demands of regulated industries.

Whether you're launching a new diagnostic cartridge or scaling a medical device, our in-house team delivers the control, speed, and traceability you need to succeed.

What Is Plastic Injection Molding?

Injection molding is a manufacturing process that involves injecting molten plastic into a precisely machined mold cavity. Once cooled and solidified, the plastic forms a finished part with high dimensional accuracy and repeatability. It is ideal for producing:

• Complex geometries

• Thin-walled parts

• Large volumes of identical components

• Cleanroom-compatible medical parts

Our Injection Molding Capabilities

1. In-House Tool Design and Fabrication

We create molds in-house, offering:

• Design for Manufacturability (DFM) consulting

• Prototype and production tooling

• Mold validation and maintenance

• Rapid turnaround and modification services

2. Material Expertise for Medical and Life Science Applications

We process a broad range of thermoplastics including:

• Polypropylene (PP)

• Polycarbonate (PC)

• ABS

• COC/COP

• TPEs and elastomers

All materials are selected for biocompatibility, sterilizability, and FDA/USP compliance.

3. ISO 13485-Certified Processes

Our injection molding operations follow documented SOPs and quality controls, including:

• IQ/OQ/PQ validation

• Batch documentation and lot traceability

• Part inspection, sampling, and DHR generation

4. Scalability and Flexibility

We mold parts in:

• Low, mid, and high volumes

• Single and multi-cavity molds

• Bridge, prototype, and commercial production settings
