We make custom bottle cap injection moulds for beverage, water, edible-oil and household packaging - from single-cavity pilot tools to multi-cavity production moulds. Tamper-evident features, linerless seal designs, in-mould closing and multi-cavity layouts are all standard work for our team.
Lead Time: T1 Samples in 30-45 Days
Simple single-cavity PP cap tools run 30-35 days to T1; multi-cavity tools with valve-gate hot runners or unscrewing mechanisms run 40-45 days. You get a firm schedule in the quotation, with DFM feedback before steel is cut.
Mould Steels We Run
Pre-hardened: P20, 738H (1.2738), 1.2311, 1.2312. Through-hardened: H13 (1.2344) at 52-54 HRC. High-gloss and corrosion-resistant: S136 (1.2083 ESR) and NAK80 - the usual choice for cap tools that run long hours and must resist wear and corrosion. Standard mould base S45C; 2085 stainless base for anti-rust requirements.
MOQ and Production Flexibility
Moulds: 1 set minimum. Caps and moulded parts: from 1,000-1,500-piece pilot runs up to monthly capacity planning in the millions.
Sample Policy
T1 machine time and basic material cost are included in the mould price - no separate trial fee. Samples ship by international courier (DHL/FedEx) at the customer cost (EXW) or as a separately quoted line. Need cap samples before the tool is cut? 3D-printed prototypes with CMF finishing are about USD 125 per set, delivered in around 5 days, 100% prepaid.
Quality Control You Can Verify
Every tool passes a fixed inspection chain: steel hardness verification, electrode measurement, core and cavity dimension measurement, then final sample measurement. Machining-only mould inserts ship with a complete CMM dimension report, 100% verified against your 3D drawing tolerances. In-house metrology: CMM (Serein, Tesa), 2D projector, hardness testers, height gauges.
Warranty and After-Sales
300,000-shot mould life warranty under normal operation and regular maintenance. Keep the mould running in our plant and daily maintenance is free for the life of the tool. If you move the mould out, settle the balance and the transfer fee, and production risk and maintenance transfer to your side.
Equipment and In-House Trial
High-speed CNC machining centres (Makino, Charmilles) with 4- and 5-axis capability, slow wire-cut EDM (WEDM-LS), precision EDM and optical curve grinding. In-house trial and small-batch production on Haitian presses from 80T to 450T - so you see real caps from the real tool before shipment.
