Solving Deep-Draw Core Shift & Rim Cooling
A 120L or 240L garbage bin has a draw depth of nearly 1 meter. Under high injection pressure, even a 0.3 mm deflection of the long male core creates uneven wall thickness, warpage, and incomplete filling.
1. Tapered Interlocks & Core Support
We machine precision 4-way tapered parting-line interlocks and zero-clearance wear blocks around the base of the core to lock the cavity and core halves rigid during high-speed HDPE injection.
2. Beryllium-Copper (BeCu) Rim & Base Cooling
The upper lifting lip (comb-lift flange) and bottom wheel-axle bosses are thick heat traps. We fit high-conductivity BeCu inserts and spiral baffle channels deep inside the core to cut 10-15 seconds off every cycle.
Air-Assisted & Hydraulic Stripper Ejection
Because HDPE shrinks tightly onto the deep male core, pushing with small ejector pins alone will punch through or white-stress the bin bottom. We combine synchronized hydraulic cylinder stripper plates around the bin rim with multi-stage compressed-air poppet valves on the core face to break the vacuum instantly upon mold opening.
Plastic Dustbin Mould FAQ
What are the specifications of a 120L or 240L dustbin mould?
A standard 120L/240L EN 840 wheelie bin mould is a single-cavity tool built in DIN 1.2738 or P20H steel, rated for 500,000+ shots, using high-flow hot runners, BeCu cooling inserts, and air-assisted hydraulic stripper ejection for UV-stabilized HDPE.
How do you prevent core shift on deep 240L garbage bin moulds?
We use heavy-duty 4-sided tapered interlocking blocks at the parting line, balanced multi-point gating at the bin base, and precision moldflow simulation to equalize melt pressure around the deep core.
Can you build moulds for both the bin body, lid, and wheels?
Yes. We supply complete turnkey tooling sets including the bin body mould, 1- or 2-cavity lid mould, and multi-cavity hinge-pin and rubber/HDPE wheel moulds.
