Injection Moulding Machine for Wall Plugs and Anchors
Wall plugs and plastic anchors are made on horizontal injection moulding machines in multi-cavity moulds, from PA6 or PA66 nylon for load-bearing plugs and PP or PE for light-duty plugs. Machine size follows the projected area of all cavities plus the runner, and the opening stroke needed to pull long core pins. Nylon must be dried before moulding.
For wall plugs, machine selection centres on steady shot control across many cavities, centred core pins and a clamp that holds fine fins without flash. Pratishna Engineers supplies horizontal injection moulding machines for wall plug and anchor production and can recommend a configuration for your plug range and mould.

Machine Requirements for Wall Plug and Anchor Moulding
Each plug is small, but its fins, split legs and screw hole have to come out the same in every cavity. Points to check when selecting a machine:
- Dryer sized for the PA6 or PA66 throughput
- Stable shot control on high-cavity cold or hot runner moulds
- Opening stroke that clears long screw-hole core pins
- Clamp that keeps thin fins and barbs free of flash
- Even mould cooling so long plugs come out straight
- Screw and barrel suited to nylon, PP and PE
Recommended Machine for Wall Plugs and Anchors
Standard wall plugs are light parts, so the E Series (75-180 T) can run many high-cavity plug moulds. Longer frame fixings, heavy-duty anchors and moulds with more cavities need a bigger platen and longer opening stroke, where the H Series (120-350 T) fits. Final tonnage is set by the projected area of cavities and runner.

FAQs / Buyer Questions
Questions plug and anchor makers ask before they buy a machine.
Which Injection Moulding Machine Is Used to Make Wall Plugs?
A horizontal machine running a multi-cavity mould. Short economy plugs often run on the E Series, while long frame fixings or very high cavity counts move to the H Series because of mould size and stroke.Should Wall Plugs Be Moulded in Nylon or PP?
Nylon PA6 or PA66 grips better in brick and concrete and holds up when the screw spreads the legs. PP and PE plugs cost less and suit light fixings. The choice depends on the load the plug is sold for.Why Does Nylon Need Drying Before Moulding Wall Plugs?
Nylon is hygroscopic and picks up moisture from the air. Moulded wet, it shows splay on the surface and gives brittle legs that crack when the screw goes in. Hopper drying keeps the granules dry up to the barrel.
What Causes Uneven Walls and Split Plugs in the Mould?
Long core pins for the screw hole can deflect under injection pressure when the plug is gated from one side, leaving one wall thin. Balanced gating, pin support and steady holding pressure keep the wall even so the plug expands evenly.Can Pratishna Recommend a Machine for My Wall Plug?
Yes. Share the plug drawing or sample, material, part weight, mould size, number of cavities, runner type and monthly quantity, and Pratishna Engineers will suggest a suitable machine.Does the Machine Suit Other Building and Construction Parts Too?
Yes. A similar machine can mould cable clips and saddles, tile spacers, faucet aerators and soap dishes, depending on the mould and material.
