Product Overview
This multi head co-extrusion blow molding machine is configured to run one to four die heads, so a single cycle can form several small containers or fewer large ones. For 10 L PE and PP containers it pairs that flexibility with a co-extrusion crosshead for multilayer structure.
A 70 mm screw feeds the head steadily, while the streamlined melt path and diffluence shuttle avoid dead angles, keeping the parison free of dark spots and stripes across every cavity.
Key Features
- One to Four Die Heads: Multi-head configuration lets the machine run multiple small containers per cycle or switch to fewer heads for larger ones.
- Co-Extrusion Crosshead: A shared crosshead supports multilayer parison structure for PE and PP containers.
- Clean Melt Path: A streamlined diffluence shuttle removes dead angles in the head, preventing dark spots and longitudinal stripes.
- Uniform Multi-Cavity Output: Microcomputer parison control keeps wall thickness even across all cavities.
- 70 mm Screw Feed: About 90 kg/h plasticizing capacity keeps every head supplied with steady, well-mixed melt.
- Double Station Shuttle Clamping: Fast, stable platen motion lifts output and protects mould alignment.
- Forty Mould Recipes: Stored settings make head and mould changes quick and repeatable.

Multi head output suits producers of matching PE and PP container families, such as small bottles and caps or a range of small jars, where several cavities in one cycle cut unit cost.
It also fits industrial and household PE and PP containers, including detergent, lubricant, and chemical packaging that benefits from a multilayer structure.
Product Q&A
Q: How many heads can the machine run?
A: It supports one to four die heads, allowing multiple small containers per cycle or fewer heads for larger containers.
Q: Which materials are supported?
A: The machine processes PE, PP, PVC, PA, PC, PS, and EVA, with PE and PP the most common for containers.
Q: How is parison quality kept clean?
A: A streamlined diffluence shuttle in the head removes dead angles, preventing dark spots and stripes on the parison.
Q: Is wall thickness even across cavities?
A: Yes. Microcomputer parison programming regulates wall thickness so all cavities stay consistent.
