Mold Design and Manufacturing—Precision Engineering for Medical-Grade Parts

In medical device production, success starts with the mold. A high-quality injection mold doesn’t just shape plastic—it shapes performance, compliance, and long-term manufacturability. That’s why choosing the right partner for mold design and manufacturing is critical, especially in regulated industries like diagnostics, biotech, and life sciences.

At Ciro Manufacturing, we offer in-house mold design, fabrication, and maintenance—giving our clients faster lead times, better design-for-manufacturability (DFM), and tighter control over quality and cost.

Why Mold Design Matters

Every component in a diagnostic kit, medical device, or biotech product must meet strict specifications for:

• Dimensional accuracy

• Material performance

• Biocompatibility and sterilizability

The mold dictates all of these. A poorly designed mold can result in flashing, warping, sink marks, or fill inconsistencies—problems that delay production, increase costs, and risk product failure.

Our Mold Design and Tooling Capabilities

1. Collaborative Design for Manufacturability (DFM)

We work closely with clients to optimize part geometry, reduce complexity, and plan for scalability. Our engineers assess:

• Gate location and flow

• Ejection strategies

• Cooling efficiency

• Tolerances for cleanroom applications

2. In-House Mold Fabrication

Our fully equipped toolroom includes:

• CNC machining and EDM capabilities

• Mold bases and custom inserts

• Multi-cavity and family mold options

• Polishing and surface finishing to medical-grade standards

3. Prototype and Bridge Tooling

We offer quick-turn tooling options for:

• Feasibility studies

• Clinical trials

• Investor demos

Bridge tools help reduce time to market while final production tools are being validated.

4. Mold Maintenance and Longevity

We maintain and repair all tools on-site, ensuring:

• Longer mold life

• Reduced downtime

• Lower long-term tooling costs

Materials Expertise

We design molds for medical-grade plastics, including:

• Polypropylene (PP)

• Polycarbonate (PC)

• COC/COP

• ABS

• Nylon and glass-filled resins

These materials are selected for biocompatibility, clarity, chemical resistance, and sterilization compatibility.

Applications We Support

• Diagnostic test housings and cartridges

• Specimen collection tubes and caps

• Swab handles and transport components

• Biotech reagent kits and fluid reservoirs

• Custom OEM parts for medical assemblies

Case Study: Complex Mold for a Lateral Flow Cassette

A client launching a lateral flow rapid test needed a multi-part housing with tight dimensional control. Ciro:

• Co-developed the part design for DFM

• Built a multi-cavity mold in under 4 weeks

• Delivered 100,000+ units within 30 days

This accelerated their validation and helped secure a key public health contract.
