Injection Moulding Machine for Air Cooler Bodies
Air cooler bodies, the cabinet and water tank, are moulded on large two-platen or toggle injection moulding machines from PP copolymer, HDPE or recycled PP blends. Cabinet footprint and tank depth set the tonnage. Long-term stress cracking of the water-filled tank matters most, with sink control on the large visible panels.
Machine selection for a cooler body depends on platen size, opening stroke for a deep tank and shot weight for a heavy part. As a maker of two-platen injection moulding machines, Pratishna Engineers can look at your cooler parts and mould and advise on the route.
Manufacturing Air Cooler Bodies?
Share your cabinet and tank drawings, material and mould sizes, and Pratishna Engineers will check the clamping force needed.
Machine Requirements for Air Cooler Body Moulding
A cooler body is a big structural moulding, and the tank holds water for months at a time. Settle these points first:
- Process route for the tank, moulded or rotomoulded
- Clamping force for the full cabinet footprint
- Opening stroke and mould height for a deep tank
- Grade resistant to stress cracking under standing water
- UV stabilised grade for balcony and window use
- Ribbed walls to avoid sink on visible panels
Recommended Machine for Air Cooler Bodies
Full cabinets and tanks need more clamping force than the Two-Platen PHM Series (160-350 T) provides, and the H Series (120-350 T) stops at the same size. Both are offered for smaller cooler parts such as louvres and grilles. Special Purpose machines are built to application. Send your cabinet and tank details on enquiry so Pratishna Engineers can advise on the options.

FAQs / Buyer Questions
Questions cooler makers raise before tooling a cabinet or tank.
Which Injection Moulding Machine Is Used to Make Air Cooler Bodies?
Large two-platen or toggle presses, sized by cabinet footprint and tank depth. The force required is beyond the PHM and H ranges, so cooler body work is discussed with the buyer before any advice is given.Should the Cooler Tank Be Injection Moulded or Rotomoulded?
Rotomoulding and blow moulding can compete for the tank at lower volumes, since their tooling costs less. Injection moulding suits higher volumes and finer detail, so the route is settled before tooling.Why Does an Air Cooler Tank Need a Stress-crack Resistant Grade?
The tank stays full of water for months, and steady load on moulded-in stress can start cracks at corners and bosses. PP copolymer or HDPE grades with good stress-crack resistance, plus generous radii, reduce that risk.
Can Recycled PP Be Used for Cooler Bodies?
Recycled PP blends are used for some cabinet parts. Melt flow and colour vary between lots, so each lot is checked, and UV stabiliser is added for coolers that sit near windows or on balconies.Can Pratishna Recommend a Machine for My Air Cooler Body?
Share the cabinet and tank drawings, material, part weights, mould dimensions and annual volume. Pratishna Engineers will review the tonnage needed and advise on options for each part.Does the Machine Suit Other Air Cooler and Fan Parts Too?
The PHM and H Series can run smaller related parts such as fan blades, fan regulators, appliance fan housings and blower scrolls, and AC grilles, subject to the mould.
