Injection Moulding Machine for Wall Plugs and Rawl Plugs
Wall plugs are moulded on horizontal injection moulding machines in high-cavity moulds, usually from PA6 or PA66, with PE and PP for light-duty plugs. Cavity count sets the clamping force and shot weight more than plug size does. Dry the nylon properly, or the plug splits when the first screw goes in.
For plug tools, the press must carry many cavities with slides or collapsing cores and fill them evenly. Pratishna Engineers supplies horizontal injection moulding machines for wall plug production and can match a machine to the cavity count of your tool.

Machine Requirements for Wall Plug Moulding
Plugs packed with furniture and wall-mount kits come from high-cavity tools with moving cores, so machine choice should cover:
- Clamping force and platen space for high-cavity tools
- Slides or collapsing cores for the split expansion zone
- Anti-rotation ribs filled fully in every cavity
- Nylon drying before moulding so plugs do not split
- Hardened hot runner parts or a cold runner layout
- Cavity balance so every plug expands the same
Recommended Machine for Wall Plugs
Small and mid-size plug tools suit the E Series (75-180 T). Higher-cavity moulds with slides move to the C Series (140-320 T), while the H Series (120-350 T) covers large multi-size tools and hot runner moulds. Tool makers often quote cavity count to suit the press, so plan the machine and the tool together.

FAQs / Buyer Questions
Questions fixing and fastener makers ask about wall plug moulding.
Which Injection Moulding Machine Is Used to Make Wall Plugs?
The machine follows the tool. A modest-cavity plug mould fits the E Series, while higher-cavity or multi-size moulds need the C or H Series for platen area and shot capacity.Why Do Nylon Wall Plugs Split When a Screw Is Driven?
Undried nylon degrades in the barrel and moulds brittle. Freshly moulded plugs are also drier and more brittle than conditioned ones, so dry the resin to the supplier limit and test split resistance after conditioning too.Should a Wall Plug Mould Use a Hot or Cold Runner?
Cold runners are often the cheaper choice at this part size, with runners reground where the customer allows. Nylon hot runners need high-hardness components and close temperature control to avoid drooling and degradation.
How Are the Expansion Zone and Ribs Formed?
The split expansion zone and anti-rotation ribs are undercuts, so the tool uses slides or a collapsing core. These moving parts add mould height and need regular cleaning to avoid flash between cavities.Can Pratishna Recommend a Machine for My Wall Plug?
Yes. Share the plug sizes, drawings or samples, material, part weight, mould dimensions, cavity count and monthly volume, and Pratishna Engineers will recommend a suitable machine.Does the Machine Suit Other Fixing and Fastener Parts Too?
Yes. Similar machines mould anchor fasteners, fastener caps, push-fit and panel clips, and knock-down fittings such as dowels and shelf pins, subject to the mould.
