Injection Moulding Machine for Fall-arrest Hardware Components
Fall-arrest hardware mouldings, such as strap keepers, back plates, pad carriers, lanyard housings and connector guards, are made on horizontal injection moulding machines in POM, glass-filled PA66, TPU or ABS. Part size and cavity count set machine size. Load path matters most: the buckles, D-rings and connectors that carry arrest load are metal.
For fall-arrest equipment, machine selection starts with listing which plastic parts sit outside the load path, then sizing for small multi-cavity tools and tough grades. Pratishna Engineers supplies horizontal injection moulding machines for these hardware mouldings and can recommend a configuration.

Machine Requirements for Fall-arrest Hardware Moulding
Plastic parts on fall-arrest gear guide, cover and protect, while metal carries the load. Machine points to check:
- Load path confirmed before quoting any moulded part
- Tough POM keepers with snap arms free of weld lines
- Glass-filled PA66 back plates with wear-resistant screw
- TPU pad carriers and guards dried before moulding
- Webbing slots with smooth, flash-free edges
- Family tools for keepers, guards and housings
Recommended Machine for Fall-arrest Hardware Components
Most fall-arrest mouldings are small, so the E Series (75-180 T) handles keeper, guard and lanyard housing tools. Back plates, larger pad carriers and high-cavity keeper moulds are sized to the C Series (140-320 T), and the widest plates to the H Series (120-350 T).

FAQs / Buyer Questions
Fall protection makers usually raise these before moulding plastic hardware parts.
Which Injection Moulding Machine Is Used to Make Fall-arrest Hardware Parts?
Keepers, guards and small housings usually run on the E Series in multi-cavity tools. Back plates, large pad carriers and high-cavity family tools move up to the C or H Series, depending on mould size.Can a Load-Bearing Buckle or D-Ring Be Moulded in Plastic?
On fall-arrest equipment the load-bearing buckles, D-rings and connectors are metal. Identify any part in the arrest load path before quoting, because a moulded part there is a certification and liability question, not a material choice.Which Material Suits Strap Keepers and Back Plates?
POM gives keepers a tough snap fit and low friction on webbing, while glass-filled PA66 suits stiffer back plates. TPU works for pad carriers and guards. Dry PA66 and TPU before moulding to avoid brittle parts.
Why Do Webbing Slots Need Close Attention?
Webbing slides through keepers and plates in daily use. Flash or a sharp parting line at a slot edge abrades the strap, so keep shut-off faces in good repair and check slot edges on first-off parts.Can Pratishna Recommend a Machine for My Fall-arrest Hardware?
Yes. Share the part list with drawings or samples, materials, part weights, mould sizes, cavities and monthly volume, and Pratishna Engineers will recommend a machine.Does the Machine Suit Other Worker Safety Parts Too?
Yes. Hard hat cradles and ratchets, composite safety footwear toe caps, ear defender headband arms and respirator strap buckles can run on similar machines, subject to the mould.
