Injection Moulding Machine for Bra and Lingerie Hardware
Bra and lingerie hardware, such as rings, sliders, hooks and clips, is produced on horizontal injection moulding machines from POM, PA6 or PA66, with many cavities per mould. Cavity count and a very small shot weight set machine size. Nylon must be moulded dry, and parts are designed to conditioned properties because they are washed repeatedly.
Selection focuses on shot precision for tiny sections, clean colour changes across a shade range and smooth edges for skin contact. Pratishna Engineers supplies horizontal injection moulding machines for lingerie hardware and can recommend a configuration for your part range and moulds.

Machine Requirements for Bra and Lingerie Hardware Moulding
These parts sit against skin and hold strap tension through many wash cycles, which narrows the process window. Points to check:
- Smooth gate vestige and edges for skin contact
- No flash on slider bars that cuts elastic
- Nylon dried before moulding to prevent splay
- Slider grip that does not creep under strap tension
- Flow marks controlled on translucent and nude shades
- Fast, clean colour changes between fabric shades
Recommended Machine for Bra and Lingerie Hardware
Lingerie parts are tiny, so the shot is small even in a mould with many cavities, and injection accuracy counts for more than clamp size. Hybrid PH (120-140 T) with electric injection suits precise multi-cavity tools, the E Series (75-180 T) runs many standard moulds, and the H Series (120-350 T) fits large hot runner tools.

FAQs / Buyer Questions
Questions lingerie hardware makers raise most when choosing a machine.
Which Injection Moulding Machine Is Used to Make Bra and Lingerie Hardware?
Small horizontal machines with precise injection. Hybrid PH and E Series machines suit typical ring, slider and hook moulds, and the H Series takes bigger hot runner tools or family moulds covering several part sizes.Why Must Nylon Be Dried for Lingerie Parts?
PA6 and PA66 absorb moisture, and wet nylon gives splay, bubbles and weak parts. After moulding the parts take up moisture again in washing, so designs are based on conditioned properties, not dry-as-moulded strength.How Are Flow Marks Kept Off Translucent Shades?
Translucent and nude tones show every flow line, weld line and gate blush. Gate size and position, steady melt temperature, a polished mould and controlled injection speed keep the surface even across all cavities.
Why Does a Bra Slider Lose Its Adjustment?
Under strap tension a slider that creeps, or a bar left thin by a short shot or sink, lets the strap slip. POM or nylon at the right section, fully packed with holding pressure, keeps the grip.Can Pratishna Recommend a Machine for My Lingerie Hardware?
Yes. Share samples or drawings of rings, sliders, hooks and clips, material, shade range, mould dimensions, cavity count and monthly volume, and Pratishna Engineers will recommend a suitable machine.Does the Machine Suit Other Garment Parts Too?
Yes. The same small machines can mould snap fasteners, plastic buttons, cord stoppers and zipper pullers, depending on the mould.
