Precision Engineering for Medical Components
Medical device projects often fail during the transition from prototype to volume production due to inadequate DFM analysis. Our engineering team reviews your CAD files specifically for medical-grade requirements, such as wall thickness uniformity, stress point reduction, and gate placement that prevents cosmetic defects on sensitive surfaces.
By identifying potential moldability issues early, we help you avoid costly tool modifications and accelerate your time-to-market. Whether you are developing a diagnostic housing or a complex surgical tool component, our focus is on ensuring the design is optimized for high-repeatability production runs.
- Wall thickness uniformity and stress point reduction
- Gate placement optimized for cosmetic surfaces
- Early DFM feedback to reduce tooling rework
Design checks before tooling
01. CAD review
Validate geometry for moldability and medical-grade tolerances.
02. Material pre-selection
Match resin properties to sterilization and biocompatibility needs.
03. Mold flow analysis
Predict filling, cooling, and warp behavior before steel is cut.

Material Selection for Healthcare Applications
Choosing the right resin is critical for medical devices that undergo sterilization or contact with biological fluids. We work with a wide range of engineering plastics, ensuring the material meets your specific biocompatibility and chemical resistance requirements.
PC (Polycarbonate)
Used for transparent covers and high-impact housings requiring optical clarity.
PEEK
Selected for high-performance structural components requiring heat and chemical resistance.
PBT
Ideal for electrical connectors and components requiring high dimensional stability.
TPE/TPU
Used for soft-touch grips, seals, and gaskets in handheld medical devices.
We assist your team in evaluating material certifications to ensure compliance with relevant industry standards before tooling begins.
Secondary Operations and Assembly
We provide a complete manufacturing workflow to reduce your supply chain complexity. After molding, we offer secondary processing to deliver parts ready for final assembly or packaging.
Ultrasonic Welding
Creating strong, airtight bonds for medical enclosures.
Threaded Insert Installation
Ensuring robust assembly points for internal electronics.
Custom Printing
Applying labels or markings required for device identification and tracking.
Clean-room-ready Assembly
Managing component sub-assemblies to minimize contamination risks.
From Prototype to Production
We support your project at every stage. If you are in the R&D phase, we provide prototype tooling to validate your design and material choice before committing to full-scale production molds.
Prototype & Validation
Prototype tooling and sample molding to prove design, material, and function before production.
Bridge Tooling
Intermediate molds that deliver production-quality parts while final high-cavitation tooling is prepared.
Volume Production
High-cavitation production molds designed for long-term reliability and consistent output.
Our project management process ensures you receive regular updates on mold progress, sample testing, and delivery timelines, providing the transparency needed to manage your product launch schedule effectively.
Request a Manufacturing Proposal
To get an accurate assessment for your medical plastic parts, provide us with your 3D models (STEP, STP, or X_T formats) and your technical requirements. We evaluate your design for manufacturing efficiency, material suitability, and expected production volume.
