Polyolefins dominate hollow-part production because they are tough, food-safe and easy to recycle, and this PE PP HDPE blow molding machine is tuned for exactly that family. With a 200 kN clamping force and a double-station layout, the PE PP HDPE blow molding machine holds large cavities shut under pressure that would otherwise flash a soft PE parison. In practice, a PE PP HDPE blow molding machine dimensioned this way produces rigid 10 L containers with clean parting lines shift after shift, and it does so without asking the operator to nurse the clamp.
Because both PE and PP process on the same PE PP HDPE blow molding machine, a moulder can quote polyolefin work of almost any wall section without changing platform. The machine also accepts PVC, PA, PC, PS and EVA when a technical part calls for it, so one investment covers a wide brief.
Material and Clamping Strengths
Clamping force is the quiet hero of polyolefin work. PE flows easily and a poorly held mould lets it escape as flash along the parting line, which wastes resin and needs trimming labour. A 200 kN clamp removes that risk on large cavities, and the toggle plus linear guide keeps the platen square as it travels, so the seam stays flat even on a 700 x 420 mm mould. That combination is what separates a reliable PE PP HDPE blow molding machine from a machine that is constantly re-shimmed.
- PE and PP native: both handle without modification.
- 200 kN clamping: firm cavity closure for large 10 L moulds.
- Double station: two platens share one head.
- Wide mould size: up to 700 x 420 mm.
- Toggle plus guide: stable platen travel for flat, flash-free seams.
Material vs Clamping
| Material | Behaviour | Clamp Fit |
|---|
| HDPE | Tough, waxy melt | 200 kN suits it |
| PP | Stiffer, higher shrink | 200 kN suits it |
| PVC | Corrosive, needs care | With tuned cycle |
| PA / PC / PS | Technical parts | With tuned cycle |
Applications
Chemical and lubricant 10 L containers, PE storage boxes and PP automotive ducts are natural work. Wide-mouth polyolefin jars and household hollow goods also run efficiently thanks to the generous platens, and the two-station cycle keeps output high when one mould suits several PE and PP jobs.
A final practical point: because PE and PP both run on the platform, spare-part and tooling decisions stay simple. A shop does not need to keep two families of hardware in the store, and a single mould library serves both resins, so overhead per job stays low even when the order mix changes.
Product Q&A
Q: Why does clamping force matter for PE and PP?
A: Soft polyolefin parisons flash easily, so the 200 kN clamp keeps big cavities sealed.
Q: Can I switch from PE to PP quickly?
A: Yes, stored recipes for each resin shorten changeover.
Q: What is the largest container?
A: Up to 10 L, depending on mould geometry.
