Injection Moulding Machine for Collar Stays, Collar Bones and Shirt Packaging Supports
Collar stays, collar bones and shirt packaging supports are made on horizontal injection moulding machines in high-cavity moulds from PP, PS or PA6. Cavity count and cycle time drive machine choice, because these parts sell by the thousand at a very low unit price. Flatness matters most, so stays do not take a set after laundering.
Selection focuses on fast, repeatable cycles with as many cavities as the clamp and shot allow, plus even cooling to keep thin strips flat. Pratishna Engineers supplies horizontal injection moulding machines for collar stay and shirt support production and can recommend a configuration for your parts and output.
Manufacturing Collar Stays?
Share your stay or support samples, material, cavity plan and daily output, and Pratishna Engineers will recommend a suitable machine.
Machine Requirements for Collar Stay and Shirt Support Moulding
With parts this simple, the margin sits in the cycle and the cavity count. What to plan for:
- Even cooling so thin stays come out flat
- Gate placed to keep flow along the stay length
- Living hinges in PP clips filled in one direction
- Short cycle with fast mould opening and ejection
- High-cavity or hot runner moulds for volume
- PA6 stays dried and designed for wash cycles
Recommended Machine for Collar Stays and Shirt Supports
These parts are light and flat, so the machine is sized by cavity count and the projected area of the runner. The E Series (75-180 T) suits many collar stay and shirt clip moulds. Wide shirt support tools, very high-cavity moulds and hot runner layouts can move to the H Series (120-350 T), where more clamp and shot are available.

FAQs / Buyer Questions
What shirt accessory makers ask when planning a new moulding line.
Which Injection Moulding Machine Is Used to Make Collar Stays and Shirt Supports?
A small to mid-size horizontal machine run for cycle time. E Series machines handle typical stay and clip moulds, and the H Series is used when a wide support tool or a large hot runner mould needs more clamping force.Why Do Collar Stays Warp or Take a Set?
Uneven cooling and flow across a thin strip leave stress that relaxes as warp, and heat in laundering can make a stay take a set. Balanced mould cooling, gating along the length and a suitable grade keep stays flat.Which Material Suits Shirt Packaging Clips?
PP is the common choice because it forms a living hinge that flexes many times. PS suits rigid clear supports and stays, and PA6 is used for stays that must handle heat and repeated washing.
How Does Cavity Count Affect the Cost per Part?
More cavities spread machine time over more parts, which matters when parts sell by the thousand. They also raise clamping force and shot weight, so mould and machine are sized together, and hot runners cut runner scrap.Can Pratishna Recommend a Machine for My Collar Stay?
Yes. Share samples or drawings of stays, bones, clips or supports, material, mould dimensions, cavity count and daily output, and Pratishna Engineers will recommend a suitable machine.Does the Machine Suit Other Garment Parts Too?
Yes. Machines of this size also suit tag pin clips, garment hanger parts, plastic buttons and belt adjusters, subject to the mould.
