Injection Moulding Machine for Inverter Bodies
Inverter bodies are moulded on large horizontal injection moulding machines, in flame-rated ABS, PC/ABS or PP, or in glass-filled PA6. Footprint sets the tonnage more than part weight, since the flat body and cover project a wide area. Many bigger covers use sequential valve gating to move weld lines and reduce warpage.
Machine selection for an inverter body looks at the widest panel, mould size between tie-bars and the hot runner setup. Pratishna Engineers supplies horizontal injection moulding machines for inverter body moulding and can recommend a configuration for your body and cover moulds.
Moulding Inverter Bodies?
Share the body and cover drawings, material and hot runner plan, and Pratishna Engineers will advise on a machine.
Machine Requirements for Inverter Body Moulding
Inverter bodies are wide, shallow flame-rated mouldings with long flow paths, so the machine has to offer:
- Tonnage sized to the full body footprint
- Tie-bar spacing that takes a wide cabinet mould
- Hot runner and sequential valve gate control
- Flame-rated grades handled without long residence time
- Even mould cooling on large flat panels
- EMI shielding method fixed before the mould is cut
Recommended Machine for Inverter Bodies
Smaller home inverter bodies and their front and top covers can fit the C Series (140-320 T). The H Series (120-350 T) takes wider bodies within its clamp and platen size. Bigger inverter cabinets, which often need more tonnage than either series offers, are reviewed with the mould on request.

FAQs / Buyer Questions
Questions inverter makers bring up about body moulding.
Which Injection Moulding Machine Is Used to Make Inverter Bodies?
For bodies within their clamp range, the C Series or H Series. Larger cabinets go past those sizes and are checked against the mould dimensions and projected area before any machine is proposed.Why Do Large Inverter Covers Use Sequential Valve Gating?
Opening gates one after another moves the melt front along the panel, reduces weld lines and lowers the pressure needed to fill. This can cut warpage and the clamp force a cover needs.How Is EMI Shielding Handled on a Plastic Inverter Body?
It is decided at design stage, either a conductive coating inside the body or a shielded internal layout. Adding it after the mould is made often means changes to ribs and fixings.
Which Material Suits an Inverter Body?
FR ABS and PC/ABS are common for cabinets that need a good finish. FR PP suits cost-driven bodies, and glass-filled PA6 is used where brackets or bases must stay stiff when warm.Can Pratishna Recommend a Machine for My Inverter Body?
Yes. Share the body and cover drawings, material, part weights, mould dimensions, gating plan and monthly volume, and Pratishna Engineers will recommend a machine or advise on larger sizes.Does the Machine Suit Other Electrical and Electronics Parts Too?
Yes. Similar machines can mould UPS housings, stabiliser housings, electricity meter boxes and distribution board enclosures, subject to the specific mould.
