Which Injection Moulding Machine Is Used to Make Temple Tips and Nose Pads?

These small soft parts usually fit the lower end of the E Series. Pratishna Engineers checks shot size against the screw and how inserts will be loaded before recommending a model.

Can Soft Tips Be Overmoulded onto a Temple?

Yes. The temple end or metal core is placed in the mould as an insert and the soft grade is moulded over it. The bond depends on the material pair and surface, so it should be tested before production.

Are Silicone Nose Pads Made on the Same Machine?

No. Silicone nose pads are moulded from liquid silicone rubber, which needs a different machine and dosing system. TPE and soft PVC pads run on thermoplastic injection moulding machines.

What Material Data Is Needed for Skin Contact?

Tips and pads touch the skin for long periods, so ask the material supplier for skin-contact compliance data on the exact grade and colour. Keep that grade fixed once samples are approved.

Can Pratishna Recommend a Machine for My Temple Tip or Nose Pad?

Yes. Share the part drawings, soft material, substrate or insert, cavity count, loading method and monthly volume, and Pratishna Engineers will recommend a suitable machine.

Does the Machine Suit Other Eyewear Parts Too?

Depending on the tool, yes. That machine class can also mould spectacle frames, spectacle cases and covers, and small lens holders and mounts.

Injection Moulding Machine for Eyewear Temple Tips, Nose Pads and Hinge Covers

Eyewear temple tips, nose pads and hinge covers are small soft parts made on horizontal injection moulding machines from TPE, TPU or soft PVC. Many are overmoulded onto a temple end or metal core, so insert handling and cavity count guide the machine. Bond strength between the soft grade and the substrate has to be proved by testing, not assumed.

Selection centres on small shots of soft material, insert loading time and flash control at shut-offs. Pratishna Engineers supplies horizontal injection moulding machines for temple tip and nose pad production and can recommend a configuration for your parts.

Machine Requirements for Temple Tip and Nose Pad Moulding

These parts touch the skin all day and must stay on the frame. Points to check before choosing a machine:

Small, repeatable shots of soft TPE or TPU
Insert loading for temple ends and metal cores
Flash-free shut-offs around the insert
Bond between soft grade and substrate tested
TPU drying and a PVC-suited screw where used
Skin-contact compliance data from the material supplier

Recommended Machine for Temple Tips and Nose Pads

Temple tips, nose pads and hinge covers are among the smallest parts in eyewear. The E Series (75-180 T) suits multi-cavity loose-part moulds and insert overmoulding tools, where loading time often sets output more than machine size. Soft PVC needs a screw, barrel and purging routine suited to PVC.

E Series - 75 to 180 tons
