Introduction to Plastic Square Container Mould
Unique Mould designs and manufactures precision plastic square container moulds for food storage, FMCG packs, household boxes, deli tubs, paint and hardware containers. Our tooling combines balanced runner design, optimized cooling, and wear-resistant steels to deliver consistent part weight, flatness, and tight snap-fit lids at high cavitation. From concept and DFM to trials and PPAP, we help brands accelerate launches with repeatable quality and low cycle times.
Working Principle and Process Flow
Square container tooling is engineered in CAD with parting lines, gating, and ejection suited to wall thickness and stacking strength. High-speed CNC and EDM machines produce cores, cavities, and inserts. Conformal and baffle cooling strategies stabilize shrinkage for flat panels and sharp radii. Moulds are validated on injection machines with resin-specific parameters, and dimensional reports confirm container-to-lid compatibility before dispatch.
Configurations We Offer for Square Container Moulds
- Single, double, and multi-cavity moulds for varied throughput targets.
- Interchangeable insert systems for quick change of capacity and logo plates.
- Hot runner valve-gate or hot-tip systems for balanced filling and low gate vestige.
- Stack mould options to boost output without increasing press size.
- Lid moulds with hinge or snap-fit designs matched to container bodies.
Key Features of Our Square Container Tooling
- Food-contact compatible surface finishes for PP, HDPE, and clarified random copolymer.
- Optimized cooling layout for fast cycles and reduced warpage on flat panels.
- Hardened tool steels and coatings on sliding areas for long tool life.
- Uniform wall-thickness and corner radii engineered for stacking load.
- Full documentation with trials, material specs, and maintenance schedule.
Applications of Plastic Square Containers
- FMCG and food storage tubs for spices, snacks, dairy, confectionery, and meal prep.
- Household organizers for kitchen, wardrobe, and utility storage.
- Industrial packaging for fasteners, paints, adhesives, and hardware kits.
- Retail display boxes with branding, in-mould labels, and tamper-evident lids.
Benefits of Choosing Unique Mould
- DFM support to reduce weight while maintaining stiffness and sealing performance.
- Short validation cycles with robust mould trials and dimensional reports.
- High uptime due to standardized components and easy maintenance access.
- Scalable cavitation and stack mould options for future capacity increases.
Why Our Plastic Square Container Moulds Stand Out
With deep category experience and modern manufacturing, Unique Mould delivers consistent lid fit, panel flatness, and visual clarity that brand owners expect. Our teams optimize cooling and gating to keep cycles low and flashes minimal, ensuring reliable production in plants across India with ongoing technical support and spares availability.
Maintenance and Safety Tips
- Clean cavities, vents, and parting lines regularly to prevent burn marks and flash.
- Monitor cooling channels for scale and flow to sustain cycle times and flatness.
- Lubricate slides and lifters with approved greases; avoid excess near cavities.
- Inspect gate areas and ejector pins for wear; re-polish as per schedule.
- Store with rust inhibitor, protective plates, and a documented service log.
