Product Overview
At the core of the MP70FS lies a 70 mm screw with a 24:1 length-to-diameter ratio, a combination chosen to deliver high plasticizing output while holding melt temperature and mixing quality under tight control. For producers of 10 L plastic bottles this means faster cycles and steadier parison weight.
The variable-frequency extrusion motor adjusts screw speed to match demand, so the machine produces only the melt it needs and trims energy use during every run.
Key Features
- 70 mm Screw, 24:1 L/D: A large-diameter screw provides about 90 kg/h plasticizing capacity for HDPE, feeding fast cycles on 10 L bottles.
- Variable-Frequency Extrusion Drive: Motor speed is electronically matched to output demand, reducing power draw while keeping melt quality constant.
- Three-Zone Barrel Heating: Twelve kilowatts of controlled barrel heat and a fan-cooled screw section keep the melt in the ideal processing window.
- Uniform Parison Weight: Microcomputer parison programming holds wall thickness steady, so bottle weight varies little from the first part to the last.
- High-Speed Shuttle Clamping: Linear-guide platens and a toggle frame shorten dry cycle time and protect mould alignment at speed.
- Zero-Flash Parting Line: A hydraulic one-way valve locks the clamping circuit after closing, removing flashes on large bottle moulds.
- Recipe Memory for 40 Moulds: The central controller stores forty mould settings, cutting changeover time between bottle sizes.

This high-output blow molding machine is aimed at beverage, dairy, and edible-oil bottles in the 1 to 10 L range, where throughput and consistent weight directly affect profitability.
It also serves chemical and household bottles such as bleach, disinfectant, and detergent packaging, where a robust screw and stable output keep production predictable.
Product Q&A
Q: Why is a 70 mm screw important?
A: The 70 mm diameter, paired with a 24:1 L/D ratio, raises plasticizing capacity to about 90 kg/h for HDPE, which is what allows fast, stable cycles on 10 L bottles without melt degradation.
Q: Does the screw speed adjust automatically?
A: Yes. The variable-frequency extrusion motor changes screw speed to match demand, so output tracks the cycle and energy use is reduced.
Q: How consistent is bottle weight?
A: Microcomputer parison control keeps wall thickness uniform, so bottle weight stays stable across a long production run.
Q: What products fit this output level?
A: Bottles and containers from roughly 1 to 10 L, including edible-oil, detergent, and chemical bottles, benefit most from this output class.
