Thin-wall uniformity (<0.8mm typical)
Flexible yet durable living hinge (PP-based)
Zero flash on sealing surfaces
High cavity count for cost efficiency
| Feature | Engineering Challenge | Our Solution |
|---|---|---|
| Integrated Living Hinge Lid | Requires precise wall thickness control (~0.2–0.3mm) to ensure flexibility without breakage over 10,000+ cycles | Proprietary gate design + optimized cooling channels + PP material simulation via Moldflow® |
| Thin-Wall Cylinder Body | Risk of warpage, sink marks, or short shots during high-speed injection | Hot runner system + sequential valve gating + real-time pressure monitoring |
| Sealing Rim & Snap Fit | Must maintain tight tolerance (±0.05mm) for leak-proof closure | CNC-machined stainless steel cores (S136/420SS) with SPI A1 mirror polish |
| High Cavity Output | Need consistent quality across 32/64 cavities | Balanced runner layout + individual cavity temperature control |
Our molds are engineered for cycle times under 8 seconds — maximizing your ROI.
| Parameter | Standard Offering | Custom Options |
|---|---|---|
| Mold Material | P20 / 718H Pre-hardened Steel | S136 Stainless Steel (for corrosion resistance & polishability) |
| Cavity Number | 16 / 32 / 64 Cavities | Up to 128 cavities upon request |
| Runner System | Cold Runner (3-plate) | Hot Runner (Yudo / Mold-Masters / Husky) |
| Ejection System | Stripper Plate + Air Assist | Sleeve Ejectors for delicate features |
| Surface Finish | SPI B1 (Textured) | SPI A1 (Mirror Polish) for optical clarity |
| Mold Life | 500,000 shots | 1,000,000+ shots with proper maintenance |
| Lead Time | 30 days (T1 sample) | Expedited 25-day option available |
| Certifications | ISO 9001 | ISO 13485, FDA Registered Facility Support |
PP (Polypropylene) – Most common for living hinges; autoclavable
PS (Polystyrene) – High transparency; ideal for visual inspection
PC (Polycarbonate) – Impact resistant; used for reusable containers
COC/COP (Cyclic Olefin Copolymer) – Low protein binding; premium IVD applications
PE (Polyethylene) – Chemical resistant; for reagent storage

We don’t just build molds — we solve production problems before they happen.
Clinical Diagnostics: Urine cups, stool containers, swab tubes
IVD Reagents: Sample vials, buffer bottles, reaction chambers
Pharmaceuticals: Pill counters, dosage cups, blister pack trays
Veterinary & Research: Tissue fixation jars, cell culture vessels
Consumer Health: Travel-sized sanitizer bottles, first aid kits
Client: Global Top 10 IVD Manufacturer (USA)
Challenge: Needed 64-cavity mold for PP specimen tubes with living hinge — previous supplier had 15% reject rate due to hinge cracking.
Our Solution: Redesigned gate location + added conformal cooling + implemented in-mold pressure sensing.
Result: Reject rate dropped to <0.5%, cycle time reduced from 12s to 7.5s, annual savings >$220K.
