Injection Moulding Machine for Toy Wheels, Axle Housings and Gears
Toy wheels, axle housings and gears are produced on horizontal injection moulding machines with multi-cavity tools, using POM for gears and PP or ABS for plain wheels. Cavity count and shot weight decide machine size more than part area. Shrinkage control at the bore matters most, because bore-to-axle clearance decides whether the toy rolls freely or binds.
Selection for these small parts centres on accurate small shots, stable mould temperature and even filling across many cavities. Pratishna Engineers offers horizontal machines, among them the Hybrid PH Series, for toy wheel and gear production and can recommend a configuration.

Machine Requirements for Toy Wheel and Gear Moulding
Wheels and gears are the working parts of a moving toy, so selection should account for:
- Small, repeatable shots for high-cavity wheel and gear moulds
- Consistent POM shrinkage so gear teeth mesh cleanly
- Round bores held to size for free-rolling axles
- Centre gating for round wheels and concentric gears
- Cavity balance so every gear in a set matches
- Stable mould temperature for repeatable bore and tooth sizes
Recommended Machine for Toy Wheels, Axle Housings and Gears
Wheel and gear moulds are compact, so machine choice follows cavity count and shot weight rather than part area. The Hybrid PH Series (120-140 T) suits precision gear moulds, the E Series (75-180 T) covers most wheel tools, while the C Series (140-320 T) takes larger wheels and the H Series (120-350 T) high-cavity layouts.

FAQs / Buyer Questions
What buyers usually ask about moulding toy wheels, axle housings and gears.
Which Injection Moulding Machine Is Used to Make Toy Wheels and Gears?
Horizontal machines sized by cavity count and shot weight. Precision gear tools suit the Hybrid PH or E Series, while bigger wheels or very high-cavity moulds move up to the C or H Series.Why Is POM Used for Toy Gears?
POM has low friction, good wear and predictable shrinkage, so teeth mesh without binding. PA6 suits tougher gears but absorbs moisture, so it needs drying before moulding and changes size afterwards.How Is Bore-to-Axle Clearance Held?
Bore size moves with small changes in shrinkage, so mould temperature, holding pressure and cooling time are fixed and checked. Core pins with their own cooling and a gate at the hub help keep the bore round.
Are Axles Moulded with the Wheels?
Usually not. Metal axles are pushed or snapped in at assembly, so the bore or axle housing needs a controlled fit. Some low-cost toys use moulded plastic axles instead.Can Pratishna Recommend a Machine for My Toy Wheels and Gears?
Yes. Share the part drawings or samples, material, part weights, mould dimensions, number of cavities and monthly output, and Pratishna Engineers will recommend a suitable machine.Does the Machine Suit Other Toy Mechanism Parts Too?
Yes. It can also mould toy vehicle chassis, doll joint parts, building blocks and board game pieces, subject to the mould and cavity count.
