Injection Moulding Machine for Chain and Conveyor Components
Chain and conveyor components such as modular belt links, chain links and flights are made on horizontal injection moulding machines, often in multi-cavity moulds, from POM, PA6, HDPE or PP. Machine size follows the link footprint, cavity count and shot weight. Shrinkage control is the main process point, so pin holes stay round and the belt does not bind.
For these parts, machine selection centres on repeatable shot weight across many cavities, even mould cooling and short cycles, since output per mould sets the margin. Pratishna Engineers supplies horizontal injection moulding machines for conveyor component moulding and can recommend a configuration for your link, mould and volume.

Machine Requirements for Conveyor Component Moulding
Conveyor links and flights are repeat parts with tight fits at the pin holes and hinge knuckles. Points to check when selecting a machine:
- Consistent holding pressure so pin holes stay round
- Even mould cooling to control shrinkage and warpage across cavities
- Shot size matched to the barrel to limit POM residence time
- Natural food-contact grades for lines carrying food
- Balanced runner or hot runner for many identical cavities
- Short, repeatable cycles since output per mould sets cost
Recommended Machine for Chain and Conveyor Components
A single link or flight is a small part, but modular belt moulds often run many cavities, and wider belt modules add projected area. Smaller link moulds suit the E Series (75-180 T). High-cavity tools and wide modules need the H Series (120-350 T) or C Series (140-320 T), chosen by mould size and shot weight.

FAQs / Buyer Questions
Questions conveyor component makers ask most when choosing a moulding machine.
Which Injection Moulding Machine Is Used to Make Conveyor Chain Links?
A horizontal machine is used. Small link moulds with fewer cavities usually sit in the E Series, while wide modules and high-cavity tools need the C or H Series. The final size comes from mould dimensions and total shot weight.Which Material Suits Conveyor Links for Food Lines?
POM and PA6 suit most chain and belt links for wear and stiffness, with HDPE or PP where impact or washdown chemicals matter. Food-contact lines need natural food-grade compounds, which often rules out filled grades.Why Do Moulded Belt Links Bind in Service?
Binding usually comes from pin holes that shrink oval, often from uneven wall thickness around the knuckle or uneven cooling. Even packing, balanced cooling and a steady mould temperature keep the holes round and the pitch consistent from link to link.
Are Conveyor Chain Guides and Wear Strips Moulded?
Straight chain guide and wear strip profiles are usually extruded, so they need a different process. Injection moulding covers the links, flights and other discrete moulded parts of the conveyor.Can Pratishna Recommend a Machine for My Conveyor Component?
Yes. Share the part drawing or sample, material, part weight, mould dimensions, number of cavities and monthly volume, and Pratishna Engineers will recommend a suitable machine.Does the Machine Suit Other Engineering Parts Too?
Yes. The same class of machine can mould related engineering parts such as cable drag chain links, sprockets and timing pulleys, castor wheels and plastic bearings, subject to the mould and material.
