Injection Moulding Machine for EV Battery Pack Housings
EV battery pack housings are moulded on large two-platen injection moulding machines, from glass-filled flame-retardant PP, glass-filled PA6 or PA66, or PC/ABS. Clamping force is driven by the projected area of the full tray, with mould size and shot weight close behind. Keeping long glass fibres intact matters most for stiffness and impact strength.
For these housings, machine selection weighs very high clamping force against platen size and opening stroke. Pratishna Engineers supplies two-platen injection moulding machines in the PHM range and can review your housing, mould and pack parts to advise on a suitable route.
Moulding EV Battery Pack Housings?
Share your housing model, material, mould size and volume, and Pratishna Engineers will review the part and discuss the options.
Machine Requirements for EV Battery Pack Housing Moulding
A pack housing is one of the largest plastic parts on an EV, and it must stay stiff, flat and flame-resistant around the cells:
- Very high clamping force for the full tray area
- Low-shear screw that keeps long glass fibres intact
- Large platens and long opening stroke for deep trays
- Short residence time for flame-retardant grades
- Flat mounting and sealing faces despite fibre warpage
- Ribbed floors filled completely without short shots
Recommended Machine for EV Battery Pack Housings
Full trays and pack covers need clamping forces well beyond the listed series ranges, so no standard model is offered for them. Share the part and mould, and Pratishna Engineers will discuss options, including whether smaller pack parts suit the Two-Platen PHM Series (160-350 T) or H Series (120-350 T), or a special purpose machine built to application.

FAQs / Buyer Questions
What EV pack developers ask before planning moulded housings.
Which Injection Moulding Machine Is Used to Make EV Battery Pack Housings?
Full housings run on very large two-platen presses, far above standard tonnage. Smaller pack parts such as module covers or cell holders can be checked against the PHM and H Series once the part and mould are known.Why Are Two-Platen Machines Used for Battery Trays?
A two-platen clamp gives large platens and a long opening stroke in a shorter machine. That suits big, deep moulds that need wide tie-bar spacing and space to remove a large tray.Which Materials Are Used for EV Battery Pack Housings?
Glass-filled flame-retardant PP, with short or long fibre, is common for trays and covers. Glass-filled PA6 or PA66 gives more stiffness and heat resistance, and PC/ABS can suit smaller covers.
Does Long Glass Fibre Need Special Processing?
Yes. Fibres break under high shear, so a low-shear screw, low back pressure and open nozzle, runner and gate sizes help keep fibre length. Shorter fibres mean a weaker, less stiff housing.Can Pratishna Recommend a Machine for My Battery Pack Housing?
Yes. Share the 3D model or drawing, material grade, part weight, mould dimensions and weight, and annual volume, and Pratishna Engineers will review it and explain what can be offered.Does the Machine Suit Other EV and Automotive Parts Too?
For smaller parts, the listed series can be considered, such as EV charging gun housings, battery containers, battery covers and automotive junction boxes, subject to the mould.
