Injection Moulding Machine for Luggage Lock Housings
Luggage lock housings, dials and shackle housings are made on horizontal injection moulding machines as small precision parts in POM, glass-filled nylon, ABS and PC/ABS. Part size and cavity count set the machine, and the moulds are small. Shrinkage consistency matters most, because dial detent feel and free play in the mechanism depend on it.
Lock mechanisms leave little room for size drift, so machine choice centres on shot repeatability and stable mould temperature. Pratishna Engineers supplies horizontal injection moulding machines for lock parts and can recommend a setup once the moulded part list is confirmed.

Machine Requirements for Luggage Lock Housing Moulding
A lock is a small mechanism, and the moulded parts decide how it feels to the user. Machine points to cover:
- Repeatable small shots for dials, buttons and sliders
- Stable mould temperature for consistent POM shrinkage
- Close control of detent features and pin bores
- Wear-resistant screw for glass-filled nylon housings
- Clean finish on visible surrounds and buttons
- Drying of nylon and PC/ABS before moulding
Recommended Machine for Luggage Lock Housings
Lock parts are small, so most dial, button and housing moulds sit on the E Series (75-180 T), often as multi-cavity or family tools. The H Series (120-350 T) applies when a larger lock housing, a high cavity count or a mould with several slides needs more platen area.

FAQs / Buyer Questions
Questions lock and luggage hardware makers bring to us.
Which Injection Moulding Machine Is Used to Make Luggage Lock Housings?
E Series horizontal machines handle most lock parts, dials through to housings. The H Series is used where the housing is larger or the mould carries more cavities and slides.Are Luggage Lock Bodies Moulded or Die-Cast?
Both are used. Many lock bodies are zinc die-cast, with only the surround, buttons and dials moulded in plastic. Confirm which parts are in scope before tools and machines are sized.Which Materials Are Used for Luggage Lock Parts?
POM suits dials, buttons and moving parts, glass-filled nylon goes where a housing takes load, and ABS or PC/ABS is used for visible surrounds. Each choice follows what the part does in the lock.
What Makes Dial Feel Vary Between Batches?
Usually shrinkage drift from changes in mould temperature, holding pressure or material moisture. Keeping these settings stable, and drying nylon before moulding, keeps detents and free play the same across batches.Can Pratishna Recommend a Machine for My Luggage Lock Housing?
Yes. Share the lock part drawings or samples, materials, part weights, mould dimensions, cavities and monthly volume, and Pratishna Engineers will recommend a suitable machine.Does the Machine Suit Other Case Hardware Too?
Yes. Similar machines can mould case latches and hinges, cord locks and toggles, zip pull tabs and bag buckles, subject to the mould.
