Injection Moulding Machine for Furniture Knobs and Handles
Furniture knobs and pull handles are moulded on small to mid-size horizontal injection moulding machines in multi-cavity moulds, from ABS, PC, glass-filled PA6 or POM. Cavity count, shot weight and any brass insert set the machine size. The show face matters most, because a thick screw boss behind it sinks unless cored and ribbed.
For cabinet knobs and handles, selection focuses on fine shot control and a stable surface for plating or painting. Pratishna Engineers supplies horizontal injection moulding machines for furniture knob and handle moulds and can suggest a machine for your design.

Machine Requirements for Furniture Knob and Handle Moulding
Knobs and handles are looked at and touched every day, so the press must handle:
- Sink-free show faces over cored and ribbed bosses
- Plating-grade ABS processing for chrome or metallised finishes
- Gate placed off the visible face of the knob
- Brass threaded inserts moulded in or pressed in after
- Glass-filled PA6 for long handles that take pull loads
- Even colour across cavities for matched handle sets
Recommended Machine for Furniture Knobs and Handles
Knobs and short pull handles suit the E Series (75-180 T) in multi-cavity moulds. Long bar handles, family tools or moulds with many inserts can need the larger platens of the H Series (120-350 T). Knobs that a customer specifies in die-cast zinc are a different process, so confirm the material before quoting.

FAQs / Buyer Questions
What furniture hardware buyers ask about knob and handle moulding.
Which Injection Moulding Machine Is Used to Make Furniture Knobs and Handles?
Small horizontal machines handle knobs and short handles, often in the E Series range. Long handles, insert-loaded moulds and family tools move up to the H Series for platen space and shot capacity.Can Moulded Furniture Knobs Be Chrome Plated?
Yes, with a plating-grade ABS and a high-polish tool. Moulding stress, weld lines and flow lines show through plating, so control injection speed and mould temperature for an even, low-stress surface.How Is a Threaded Insert Added to a Knob?
A brass insert is either placed in the mould and moulded in, or pressed in after moulding. Moulding in adds loading time and needs secure insert pins, while pressing in adds a separate assembly step.
Are Furniture Knobs Always Plastic?
No. Some decorative knobs are die-cast zinc rather than moulded. Confirm the material with your customer before quoting, since a zinc design changed to plastic needs new wall and boss design.Can Pratishna Recommend a Machine for My Furniture Knob or Handle?
Yes. Share the drawing or sample, material, finish, insert details, part weight, mould dimensions, cavity count and volume, and Pratishna Engineers will recommend a suitable machine.Does the Machine Suit Other Furniture Hardware Parts Too?
Yes. Machines in this range also mould coat hooks and wall-mount fittings, door catch and bumper housings, fastener caps and hinge parts, subject to each mould.
