Plastic Square Container Mould

Plastic Square Container Mould

A PlasticSquare Container Mould is a precision-engineered tool used in injection molding machines to produce square-shaped plastic containers. These containers are widely used in packaging applications for food, household goods, industrial parts, and more. The mould is usually made from high-grade tool steels (like P20, H13, or S136) to ensure durability, precision, and long service life.

This mould consists of a core and cavity set, cooling channels, ejector systems, and alignment locks, and is designed to deliver consistent container dimensions, smooth finishes, and minimal cycle times. It can produce containers with or without lids and may support single or multi-cavity designs depending on production needs.

Top 10 FAQs about Plastic Square Container Mould

What materials are used to manufacture the mould?
High-strength tool steels like P20, H13, or stainless steel (S136) for high wear resistance and long life.
What plastic materials can be used in this mould?
Common plastics include PP (Polypropylene), HDPE, LDPE, and PET, depending on the end-use.
What is the typical life of a plastic square container mould?
With proper maintenance, high-quality moulds can produce over 500,000 to 1,000,000 cycles.
Can the mould be customized for branding or labeling?
Yes, inserts or engraving can be added to include logos, text, or QR codes.
Is the mould compatible with hot runner systems?
Yes, it can be designed with hot or cold runner systems depending on production volume and cost preference.
How long does it take to manufacture a mould?
Typically between 4 to 8 weeks, depending on the complexity and number of cavities.
Can this mould be used for both food and non-food containers?
Yes, the mould can produce food-grade or industrial-grade containers, depending on the material used.
How do I maintain the mould for longevity?
Regular cleaning, lubrication, inspection for wear, and proper storage when not in use are key.
Can I produce containers of different sizes in the same mould?
Usually no, but interchangeable inserts can be used for small size variations.
Is there a minimum order quantity for mould production?
Mould manufacturers usually accept custom orders, but MOQ policies vary by supplier.
