Injection Moulding Machine for Camera Module and Sensor Lens Barrels
Camera module and sensor lens barrels are micro mouldings, made on small injection moulding machines from LCP, PPA or PC, often in multi-cavity moulds. Shot volume against screw size matters more than clamping force. Thread and lens seat tolerances are very tight, so metering accuracy and a stable process decide the scrap rate.
Machine selection here starts with the smallest screw that meters the shot repeatably. Pratishna Engineers supplies vertical and horizontal injection moulding machines at the small end of its range and will look at your barrel before proposing a configuration.
Moulding Camera Lens Barrels?
Share your barrel drawing, resin, tolerances and cavity plan, and Pratishna Engineers will check which machine fits.
Machine Requirements for Camera Lens Barrel Moulding
Lens barrels for phones, cameras and sensors are tiny, and small process shifts show up as focus errors. Points to check:
- Small screw diameter matched to a very small shot
- Repeatable metering and short residence time for LCP
- Thread and lens seat geometry held cavity to cavity
- Venting at fine thread roots to avoid burn marks
- Drying of LCP, PPA and PC before moulding
- Clean moulding area and handling for camera assemblies
Recommended Machine for Camera Lens Barrels
Pratishna’s smallest machines are the Vertical PV Series (40-55 T) and PVDL Series (40-80 T), which can suit small multi-cavity barrel moulds or insert work. The E Series (75-180 T) takes larger multi-cavity tools. Barrels that need milligram-level metering usually run on dedicated micro moulding machines, so share the part for a check first.

FAQs / Buyer Questions
What camera module and sensor makers ask before choosing a machine for lens barrels.
Which Injection Moulding Machine Is Used to Make Camera Lens Barrels?
Dedicated micro moulding machines are common for the smallest barrels. For larger barrels and multi-cavity tools, Pratishna Engineers would look at the PV and PVDL vertical machines or the E Series after reviewing shot volume and tolerances.Why Does Shot Size Matter More Than Tonnage Here?
A barrel weighs very little, so on a large screw the shot is a tiny fraction of capacity and dosing drifts. Material also sits longer in the barrel and can degrade. A small screw gives repeatable metering.Which Material Is Used for Camera Lens Barrels?
LCP flows into thin walls and fine threads and holds size through reflow soldering. PPA is chosen for heat resistance and stiffness, and PC for less demanding barrels. Black grades limit stray light.
Is a Clean Moulding Area Needed for Lens Barrels?
Usually, yes. Dust or fibres on a barrel can end up inside the sealed camera module. Buyers often ask for a clean moulding area, covered conveyors and clean packing as part of supply.Can Pratishna Recommend a Machine for My Camera Lens Barrel?
Yes. Share the barrel drawing, resin grade, part weight, thread and seat tolerances, cavity count and annual volume, and Pratishna Engineers will check which machine fits.Does the Machine Suit Other Precision Optical Parts Too?
Depending on size, yes. Optical fibre connector housings, lens holders and mounts, and small optical lenses are related parts, each checked against its own mould and shot volume.
