Injection Moulding Machine for Lamp Holders and Ceiling Roses
Thermoplastic lamp holders and ceiling roses are made on horizontal injection moulding machines from heat-resistant PBT, PET or PC grades. Cavities per mould, thread or bayonet features and cover diameter decide the machine. Heat-resistant grades need correct drying, because moisture lowers strength in a part that runs warm next to the lamp.
Selection for these parts weighs unscrewing or side actions, small accurate shots and drying of polyester grades. Pratishna Engineers supplies horizontal injection moulding machines for lamp holder and ceiling rose production and can recommend a configuration for your moulds.

Machine Requirements for Lamp Holder Moulding
Lamp holders carry the lamp and contacts close to heat, and ceiling roses hold terminals and the cord. Machine points include:
- Unscrewing cores for threaded holder shells and covers
- Side action for bayonet slots in the holder sleeve
- Drying of PBT and PET before moulding
- Contact and terminal pockets moulded to size
- Rose covers free of sink and flow lines
- Clean thread starts without flash at the parting line
Recommended Machine for Lamp Holders and Ceiling Roses
Holder bodies, sleeves and small roses are compact parts that fit the E Series (75-180 T), including many unscrewing moulds. Large roses, batten holder bases or high-cavity unscrewing tools that need more mould height and platen space are matched to the H Series (120-350 T) or C Series.

FAQs / Buyer Questions
What lamp holder and ceiling rose makers usually ask us.
Which Injection Moulding Machine Is Used to Make Lamp Holders and Ceiling Roses?
The E Series covers most holder and rose moulds. Bigger roses, batten holder bases and high-cavity unscrewing moulds may need the C or H Series for mould height and clamp.Can Bakelite or Urea Lamp Holders Be Made on These Machines?
Bakelite and urea are thermosets, usually compression moulded, so they do not run on a thermoplastic machine. PBT, PET and PC holders run on standard horizontal machines.How Are Threaded Lamp Holders Moulded?
Internal threads in the holder shell and cover are released by an unscrewing core turned by a motor or hydraulic drive. The machine needs the circuit and mould height for that drive.
Which Grade Suits Holders Near Hot Lamps?
Heat-resistant PBT and PET grades, often glass-filled, are chosen where the holder runs warm. PC suits covers and roses away from the heat. Grade decides drying and melt settings.Can Pratishna Recommend a Machine for My Lamp Holder?
Yes. Share drawings or samples of holder, sleeve and rose parts, material grade, part weights, mould dimensions, cavities and output target, and Pratishna Engineers will recommend a machine.Does the Machine Suit Other Electrical Building Products Too?
Yes. Similar machines can mould plug tops, terminal blocks, switch contact carriers and junction boxes, depending on the mould.
