🏭 What are HDPE Blow Moulds?

HDPE blow moulds are specialized tooling used to manufacture hollow plastic products from High-Density Polyethylene (HDPE) material. HDPE is one of the most widely used thermoplastics for blow moulding due to its excellent chemical resistance, high strength-to-density ratio, durability, and cost-effectiveness.

At Laxmi Micro Industries, we have been manufacturing high-precision HDPE blow moulds since 1987. Our moulds are engineered for uniform wall thickness, high output rates, corrosion resistance, and extended service life. We serve industries including chemicals, lubricants, pharmaceuticals, and industrial packaging.

❓ Frequently Asked Questions About HDPE Blow Moulds

1. What is the difference between HDPE and LDPE for blow moulding?
HDPE (High-Density Polyethylene) is stronger, more rigid, and has better chemical resistance, making it ideal for jerry cans and industrial containers. LDPE (Low-Density Polyethylene) is more flexible and used for squeeze bottles. Our HDPE blow moulds are specifically designed for HDPE material properties.
2. What is the typical lead time for an HDPE blow mould?
Our standard lead time for HDPE blow moulds is 15-25 days from design approval, depending on complexity, size, and cavity count.
3. What is the maximum container size you can produce moulds for?
We manufacture HDPE blow moulds for containers up to 50 litres capacity, including jerry cans and industrial drums.
4. Can you manufacture HDPE blow moulds for food-grade applications?
Yes, we manufacture HDPE blow moulds for food-grade applications including milk bottles, juice containers, and edible oil bottles using FDA-compliant materials.
5. Do you provide trial runs before dispatch?
Yes, every HDPE blow mould undergoes live trial runs on blow moulding machines. We provide sample products and a trial report before final dispatch.
6. What is the expected life of your HDPE blow moulds?
Depending on the steel grade selected, our HDPE blow moulds can produce 1 million to 5 million+ shots. We recommend H13 steel for maximum mould life.
7. Can you manufacture HDPE blow moulds with handles?
Yes, we specialize in handleware HDPE blow moulds for containers with integrated handles, commonly used for jerry cans and industrial containers.
