Injection Moulding Machine for Curtain Brackets
Plastic curtain brackets are moulded on horizontal injection moulding machines in glass-filled PA6, ABS, PP or POM. The bracket arm length, cavity count and shot weight set the machine size, and glass-filled grades also need a wear-resistant screw. The bracket carries the rod load and stays in view, so strength and surface finish are balanced.
Curtain brackets combine a loaded arm with screw bosses and a visible face, so machine selection looks at material handling for filled nylon, drying and shot control. Pratishna Engineers supplies horizontal injection moulding machines for bracket production and can recommend a configuration for your part.

Machine Requirements for Curtain Bracket Moulding
A curtain bracket holds the rod weight for years and is seen every day, so moulding needs to cover:
- Wear-resistant screw and barrel for glass-filled PA6
- Dryer sized for nylon before it reaches the hopper
- Screw bosses matched to the supplied wall plug
- Weld lines kept away from screw holes and arm root
- Hot mould surface to keep glass fibre off the face
- Ribbed arm design in unfilled grades for stiffness
Recommended Machine for Curtain Brackets
Single-cavity and low-cavity bracket tools sit comfortably in the E Series (75-180 T). Long projection brackets, family moulds that pair the bracket with its cover cap, or high-cavity tools may need the larger platen and shot of the H Series (120-350 T).

FAQs / Buyer Questions
Questions curtain bracket makers ask about material and machine.
Which Injection Moulding Machine Is Used to Make Curtain Brackets?
Bracket tools of normal size run on the E Series, fitted for the chosen material. Longer brackets, family moulds or high-cavity tools move up to the H Series for more platen space.Why Does Glass Fibre Show on the Bracket Surface?
Fibres near the surface show when the mould is cool or the fill is slow. A hotter mould and faster injection help. Where the face must look clean, paint the bracket or use an unfilled grade with ribs.Does Glass-Filled Nylon Wear the Machine?
Glass fibre is abrasive, so a wear-resistant screw, barrel and check ring are advised for regular glass-filled PA6 production. Standard screws and barrels wear faster and lose shot consistency over time.
How Is Bracket Pull-Out Strength Checked?
Brackets are tested fixed with the wall plug and screw they ship with, so boss diameter and depth must match that plug. Weld lines at the screw hole and undried nylon are common causes of failure.Can Pratishna Recommend a Machine for My Curtain Bracket?
Yes. Share the bracket drawing or sample, material, part weight, load requirement, cavity count and mould dimensions, and Pratishna Engineers will recommend a suitable machine.Does the Machine Suit Other Curtain Hardware Too?
Yes. The same machines can mould curtain rings, curtain ornaments, plastic hooks and clothes hangers, depending on each mould.
