Blow molding technology for customized hollow-body solutions

Extrusion blow molding

Extrusion blow molding is a specialized manufacturing process in which dimensionally stable hollow bodies are produced from thermoplastic materials.

Thanks to our decades of experience in the design and processing of plastics, we manufacture products based on blow-mold designs that, due to their many advantages, have become indispensable in numerous industrial sectors. Similar to plastic injection-molded products, they offer high stability while remaining lightweight and are a cost-efficient alternative to comparable products made from other materials. As a manufacturer of high-quality extrusion blow molds, we are at your side.

The Project Process for Your Success

B&W blow-mold designs are custom-made solutions developed and manufactured according to customer specifications.

Our range of services as a manufacturer includes:
- Detailed project planning in advance
- Design and construction of the tool for part production
- If required, production of a prototype
- Meticulous quality inspections
- The actual manufacturing process
- Subsequent logistics

By using thermoplastic polymers (plastics that can be reshaped when heated), we can manufacture extrusion blow-molded products with Class A visible-surface quality and more complex geometries. The finished extrusion blow-molded products from B&W are produced in a material- and resource-efficient manner and stand out for their perfection.
The dimensionally stable hollow bodies are manufactured using so-called accumulator-head large blow-molding systems. These are specialized extrusion blow-molding machines for forming hollow bodies, which implement the products designed on the computer with the highest precision and bring them into shape.

Partnership-based development and joint project management

Our extrusion blow-molded products

We manufacture a wide range of high-quality extrusion blow-molded products in large and small formats for international customers. These include automotive groups and suppliers, stadium and arena outfitters, as well as companies in the furniture sector and the packaging industry. In the production of extrusion blow-molded products, we also aim to address and serve both large and small customers with our specialization in small to medium batch sizes (order quantities of up to several 100,000 parts).
Examples of dimensionally stable hollow bodies from B&W include, in addition to industrial cases and packaging solutions, canisters, speaker enclosures, subwoofers, air ducts, hot-water collectors, climate modules, stadium seats, chairs, exhaust routing in heating systems, hospital beds, pedal cars, or furniture components.
