Yarn Package Moulds
SINOMOULD is a professional yarn package mould manufacturer in China, providing injection moulds for yarn cones, bobbins and spools used in the textile industry. Our yarn package moulds support 2-48 cavity production with a 4-10 week delivery and a 3-year warranty, including free spare parts.
What Are Yarn Package Moulds
A yarn package mould is an injection mould used to produce plastic yarn carriers, including cones, bobbins and spools. These carriers must be dimensionally accurate with a smooth, burr-free surface so that yarn winds evenly and unwinds smoothly during spinning, winding, dyeing and weaving. With imported mould steel and mirror-polished cavities, SINOMOULD ensures every yarn package mould runs consistently over a long service life.
Yarn Package Types We Produce
| Yarn Cone | Tapered yarn tube – commonly used for winding/twisting, multicavity automatic demolding |
|---|---|
| Yarn Bobbin / Tube | Cylindrical yarn tube – for dyeing and warping, slender core |
| Yarn Spool | H-shaped spool – for industrial wire winding |
| Cop / Pirn | Weaving weft small package – thinwall precision |
Mould Technical Highlights
- Multi-cavity design: 2-48 cavities available for high output per shot and lower unit cost
- Hot runner system: shorter cycle, less runner waste, ideal for long thin-walled yarn tubes
- Automatic ejection and core-pulling for slender cores, preventing deformation during demoulding
- Mirror-polished cavities: burr-free yarn contact surfaces for smooth unwinding
- Optimised cooling channels: shorter cycle time and higher productivity
- Imported mould steel: 2344 / 718H, hardened to HRC48-52 for long life
