Texin — Injection Molded Medical Face Mask: Precision, Biocompatibility, Reliable Supply

At Texin we design and manufacture high‑quality injection molded medical face mask solutions for clinical, hospital and patient‑care applications. An injection molded medical face mask must meet exacting demands — tight dimensional control, stable sealing, biocompatibility and sterilization compatibility — and that’s where our tooling, process know‑how and production systems make the difference.

Why injection molded medical face masks are demanding

• Materials and fit: Rigid support frames (PC/PA) and soft sealing surfaces (LSR or medical‑grade TPE) must mate precisely to ensure an airtight seal and user comfort.
• Process control: Thermoplastics like PC need post‑mold annealing to avoid cracking or surface fogging; soft elastomers (LSR) require precise A:B metering and cure control for consistent Shore hardness and biocompatibility.
• Clean production and traceability: Medical masks often require controlled environments and full batch records to support ISO/medical device traceability.

Texin capabilities (what we bring)

• Tooling: Precision CNC‑machined tool steel molds, EDM and high‑quality polishing ensure cavity geometry and surface finish meet medical tolerances.
• Process know‑how: Multi‑stage injection, segmented holding pressure and extended cooling are applied to reduce internal stress, control warpage and secure dimensional stability. For PC support parts we use controlled annealing to prevent cracking and haze.
• LSR overmolding and insert molding: We handle LSR-to-plastic bonding (A:B metering, 1:1 mix ratios where specified) and insert molding with appropriate surface treatments or primers as required.
• Auxiliary systems: central material supply for 24/7 unmanned runs, stable mold temperature control (chillers/modular mold‑temp units), dehumidification to control resin moisture, and weigh‑mix systems with high accuracy (mix precision down to ~5‰) for repeatable formulations.
• Testing and compliance support: dimensional inspection (CMM), leak/seal tests, biocompatibility screening (ISO 10993 scope), and third‑party testing coordination (SGS, Intertek) on request.

Common customer & producer questions — concise answers

Q: What materials do you use for injection molded medical face masks?
A: Typical builds use medical‑grade PC or PA for support frames and LSR or medical TPE for soft seals. LSR offers excellent biocompatibility and heat/aging resistance; PC offers structural strength and optical clarity for visors.

Q: How do you prevent cracking or fogging on a PC oxygen/respirator support?
A: We control injection profiles, apply segmented holding pressure, lengthen cooling for uniform mold temperature, and run a controlled annealing/post‑mold process to relieve internal stress — this reduces cracking and surface haze risk.

Q: How accurate is LSR mixing and metering?
A: We use precision two‑component metering systems; standard practice is 1:1 A:B for many LSR systems, and weigh‑mix equipment with mix accuracy down to ~5‰ for colorants/additives when needed.

Q: Do you support cleanroom molding and sterilization validation?
A: Yes. We can operate in controlled environments (ISO 7/8 as project requires), and validate compatibility with common sterilization methods (ETO, gamma, or steam) per customer specification and testing protocols.

Q: What testing and documentation can Texin provide?
A: We provide dimensional reports (CMM), functional leak/seal test data, process records, material certificates, and can coordinate third‑party chemical/biocompatibility testing (SGS/Intertek) on request.
