500ml Square Box Mould
SINO MOULD specializes in R&D and manufacturing of 500ml square box moulds for transparent PP disposable food packaging thin‑wall containers. Wall thickness can be as thin as 0.35‑0.8mm, with high transparency, food‑grade safety and temperature resistance from ‑18℃ to +121℃. The mould adopts thin‑wall high‑speed injection technology, significantly reducing material costs and enabling efficient automated production.

Key Quality Points of 500ml Square Box Moulds
Premium Steel Selection: Cavity&core use S136/2344 mirror polished stainless steel, ensuring long life and stability under high‑speed operation. SINO MOULD has established “Material Inventory Standards for Disposable Thin‑wall Container Moulds” and ships spare parts together with the mould for easy maintenance.
Mirror Polishing & Surface Quality: Cavity surface achieves high mirror grade, ensuring glossy, flawless transparent PP parts, eliminating weld lines, sink marks and flow marks.
Exclusive Zero‑Degree BeCu System: Specially designed for thin‑wall moulding, the zero‑degree BeCu system greatly improves thermal conductivity and structural stability, accelerates cooling, shortens cycle time and effectively prevents warpage.
Customized Cooling System: Based on the rapid forming characteristics, we design dense and uniform cooling channels, ensuring balanced temperature across all areas, quickly removing heat, guaranteeing surface finish and reducing sink marks and gas traps.
Precision Venting System: Venting depth is typically controlled at 0.015mm. Precision machining and strict inspection ensure venting accuracy, preventing flash or unstable injection, and ensuring perfect filling for multi‑cavity moulds.
High‑Precision Machining Control: Advanced processes including CNC precision machining and 5‑axis simultaneous machining achieve key dimensional tolerances of ±0.005mm. After semi‑finish milling, core and cavity inserts are automatically fixed, cleaned, dried and dimensionally inspected on the intelligent production line.
Precision Machining Highlights for 500ml Square Box Moulds
- CNC high-speed precision machining with critical dimensional tolerances controlled to ±0.01 mm ensures high mould accuracy.
- Multi-process inspection, including concentricity, bore diameter, length, and wall thickness, guarantees high-quality centrifuge tube moulds.
- Ultra-precision polishing ensures smooth inner bore surfaces, reducing liquid adhesion and residue build-up.
- Wear-resistant reinforced slides and ejection systems ensure stable and durable operation of the centrifuge tube moulds under high-frequency production.
Mould Flow Analysis for 500ml Square Box Moulds
Using Mouldflow analysis, we optimize the filling, packing, and cooling processes of the 500ml Square Box mould. The analysis simulates the injection moulding process, optimizing cavity layout, gate positions, and temperature control solutions, ensuring uniform cavity filling and reducing air pockets, warping, and short shots, enhancing the moulding stability of the 500ml Square Box mould.
