Medicine plastic mould

When sourcing medical-grade moulds, the steel grade is the most critical factor; prioritize S136, H13, or 718H stainless steel for high corrosion resistance and durability. Ensure the mould supports multi-cavity designs (e.g., 16, 32, or 48 cavities) to maximize production efficiency. Additionally, verify that the hot runner system (such as Yudo or Husky) is compatible with medical resins like PP, PE, or PC to ensure precise shot weight and minimal waste.

Suppliers must demonstrate compliance with ISO 13485 (Medical Devices Quality Management Systems). Since these moulds are often used in Class 100,000 cleanrooms, the mould design must be oil-free and rust-proof. Request documentation proving the use of non-toxic lubricants and ensure the final plastic parts can pass FDA or CE certification requirements for medical safety.

A professional-grade medicine plastic mould should have a mould life of at least 1 million shots. The cycle time is another vital benchmark; for thin-walled medical components, look for designs that achieve a cycle of under 10 seconds. Furthermore, the dimensional tolerance must be strictly controlled within ±0.01mm to ensure the perfect fit of medical assemblies like syringes or IV components.

These moulds are primarily used for high-precision consumables including syringe barrels, IV drip chambers, blood collection tubes, pill bottles, and inhaler components. They are also essential for producing diagnostic test kits and laboratory disposables where high-volume consistency is mandatory.

Always mandate a T1 sample test before final shipment. You should request a video of the mould trial run and a dimension inspection report (FAI - First Article Inspection). For high-value orders, consider hiring a third-party inspector to verify the steel hardness and mould operation at the factory in China before the final balance payment.

Focus on the Total Cost of Ownership (TCO) rather than just the initial price. Negotiate for a longer warranty period (e.g., 2 years) and the inclusion of critical spare parts (like heaters, nozzles, and ejector pins) at no extra cost. Mention that you are looking for a long-term partner for Made-in-China.com verified gold suppliers to leverage better payment terms like 30% deposit and 70% after sample approval.

Moulds are heavy and prone to rust during sea transit. Ensure the supplier applies anti-rust oil to all surfaces and uses vacuum-sealed plastic wrapping. The mould must be secured in a fumigated wooden box with reinforced steel straps. For customs clearance, ensure the HS Code (typically 848071) is correctly declared to avoid tariff delays.

Utilize the secured payment services provided by reputable platforms like Made-in-China.com to protect your funds until the shipping documents are verified. Avoid using private bank accounts; always ensure the beneficiary name matches the company name on the business license and the Proforma Invoice.
