Injection Moulding Machine for Hollow-Wall Anchor Fasteners
Hollow-wall anchor fasteners are produced on horizontal injection moulding machines from PA6, PA66, PP or PE, usually in multi-cavity moulds fitted with core pulls. Cavity count and the slides needed for the expansion legs decide machine size. Drying nylon before moulding matters most, as pull-out strength depends on it.
Selection for anchors centres on mould space for core-pull tools and on consistent shots that keep pull-out load steady. Pratishna Engineers supplies horizontal injection moulding machines for hollow-wall and toggle anchor production and can propose a configuration around your anchor range.

Machine Requirements for Anchor Fastener Moulding
Anchors are sold on a tested pull-out load, so the machine must repeat the same part shot after shot. Points to plan for:
- Core pull circuits for slides forming expansion and folding legs
- Dryer sized to keep PA6 and PA66 dry before moulding
- Stable shot weight so pull-out load does not drift
- Controlled regrind use, with retesting after any change
- Thin hinge zones on toggle legs filled without weld lines
- Mould height and tie-bar space for multi-slide tools
Recommended Machine for Anchor Fasteners
Anchor fasteners are small, but core pulls and slides make their moulds larger than the part suggests. The E Series (75-180 T) suits many plasterboard and hollow block anchor moulds. Toggle and folding anchors in high-cavity tools with several slides may need the larger platen and opening stroke of the H Series (120-350 T).

FAQs / Buyer Questions
Questions fixing makers ask about moulding hollow-wall and toggle anchors.
Which Injection Moulding Machine Is Used to Make Anchor Fasteners?
Plasterboard and hollow block anchor moulds often run on the E Series. Moulds with several slides or many cavities can need the H Series for platen space. Core pull circuits on the machine should match the number of slides.Why Must Nylon Anchors Be Tested After Conditioning?
Dry-as-moulded nylon is stiffer and more brittle than nylon that has taken up moisture in use. Pull-out and folding tests on conditioned parts show how the anchor behaves in the wall, so design on conditioned values.Does Changing Material or Regrind Affect the Anchor Rating?
Yes. Pull-out load is the published rating, so a new grade, supplier or regrind ratio means retesting before release. Hold the material and regrind ratio fixed once a batch passes.
How Does an Anchor Differ From a Plain Wall Plug in Moulding?
A wall plug expands inside a solid wall and has simpler geometry. Hollow-wall and toggle anchors fold or spread behind the board, which needs slides or core pulls and thin hinge sections that must fill without short shots.Can Pratishna Recommend a Machine for My Anchor Fastener?
Yes. Share the anchor drawing or sample, board type, material, part weight, number of slides and cavities, mould size and monthly quantity, and Pratishna Engineers will recommend a machine.Does the Machine Suit Other Fixing and Fastener Parts Too?
Yes. Wall plugs, push-fit panel clips, knock-down fittings and coat hook brackets can use the same machines, subject to each mould and shot size.
