Injection Moulding Machine for Yarn Guides, Tensioners and Traverse Parts
Yarn guides, tensioner discs and traverse components are made on horizontal injection moulding machines from POM, glass-filled PA66, PBT or PPS. These are small parts, so cavity count and shot accuracy set the machine size. Running yarn wears any rough spot, so the yarn path must be smooth and free of parting lines and gate marks.
For yarn path parts, machine selection weighs small repeatable shots, mould temperature control for PPS and filled grades, and wear protection for glass fibre. Pratishna Engineers supplies horizontal and Hybrid PH injection moulding machines for these textile parts and can recommend a configuration.

Machine Requirements for Yarn Guide and Tensioner Moulding
Running yarn turns any surface defect into a fibre break, so the process for these parts needs:
- Smooth yarn path with no parting line or gate mark
- Resin-rich surface on glass-filled guides to protect yarn
- Hot mould capability for PPS parts
- Flat tensioner discs with consistent part weight
- Dried PA66 and PBT before moulding
- Accurate small shots across multi-cavity tools
Recommended Machine for Yarn Guides and Tensioners
For multi-cavity guide and tensioner tools, where shot repeatability decides part weight, the Hybrid PH Series (120-140 T) is the first choice. Smaller tools fit the E Series (75-180 T). Larger traverse parts and family moulds suit the C Series (140-320 T), and the biggest tools the H Series (120-350 T). Glass-filled and PPS work calls for a wear-resistant screw and barrel.

FAQs / Buyer Questions
Questions textile machine builders and spares makers ask about these wear parts.
Which Injection Moulding Machine Is Used to Make Yarn Guides and Tensioners?
Small parts in multi-cavity tools, so cavity count picks the size. High-cavity work can lead on the Hybrid PH Series, smaller tools sit on the E Series, and large traverse parts move to the C or H Series.Are Ceramic Yarn Guide Eyes Injection Moulded?
No. The hardest-wearing guide eyes are ceramic and are not moulded. They are bought in and fitted into a moulded plastic holder, which is the part made on the machine.Which Plastic Wears Least in the Yarn Path?
POM gives low friction for many guides. Glass-filled PA66 and PPS add stiffness and heat resistance, but exposed fibre can scratch yarn, so a hot mould is used to leave a resin-rich surface.
Why Must Tensioner Discs Have the Same Weight?
Disc mass and flatness set the tension applied to the yarn. Weight checks per cavity, even cooling on both faces and steady holding pressure keep every disc within the same range.Can Pratishna Recommend a Machine for My Yarn Guide or Tensioner Part?
Yes. Share the part drawings or samples, materials, part weights, number of cavities, mould dimensions and annual quantity, and Pratishna Engineers will suggest a suitable machine.Does the Machine Suit Other Textile Machine Spares Too?
Yes. Similar machines produce sewing machine bobbins, cone holders, creel pegs and sliver can castors, depending on the mould.
