Manufacturer of blow-molded hollow-body parts
This process combines plastic extrusion with blow-molding. The parison (tube of extruded material) is enclosed in a mold in 2 half-shells of the desired shape, then blown onto the tempered walls to set the plastic in its final form. For certain product features or functionalities, the design of the tooling is more or less complex, with movements, punching, cut-outs, rework masks with partial or complete stripping of the part… overmolding of inserts can also be carried out.
Extrusion blow molding is used to manufacture hollow bodies such as plastic tanks. Thanks to this technology, we can cover 95% of your production needs for plastic components ranging from 5mL to 200L, from standard plastics bottles to the most elaborate technical ducts. To achieve this, we have at our disposal a range of continuous blow molding, accumulation blow molding and 3D suction blow molding machines.
Manufacturer of Hollow Plastic Parts by Extrusion Blow Moulding
Extrusion blow moulding is a plastic processing technology used to manufacture hollow plastic parts, ranging from small technical bottles to large industrial tanks and reservoirs.
This process combines plastic extrusion and blow moulding technologies. A parison, which is a tube of molten extruded plastic, is placed inside a mould consisting of two mould halves. Compressed air is then introduced into the parison, forcing the material against the temperature-controlled mould walls and ensuring the final geometry and mechanical performance of the part.
Thanks to our tooling design expertise, we can develop moulds and parts incorporating complex features such as:
- Mold movements and side cores
- Integrated punching and trimming operations
- Partial or complete deflashing
- Secondary machining operations
- Insert overmoulding (metallic or plastic inserts)
- Complex geometries for demanding industrial applications
