Injection Moulding Machine for Tile Spacers and Levelling Clips
Tile spacers and levelling clips are moulded in PP or PE on horizontal injection moulding machines, often in very high-cavity moulds because the parts are small and disposable. Machine size comes from the projected area of all cavities and the runner, shot weight and how cleanly parts eject. Gap thickness must match in every cavity, so cavity balance matters.
With spacers and clips, machine selection turns on clamp force for a large cavity field, a repeatable cycle and reliable ejection of many small parts. Pratishna Engineers supplies horizontal injection moulding machines for tile spacer and levelling clip moulding and can recommend a configuration for your output.

Machine Requirements for Tile Spacer and Levelling Clip Moulding
Spacers set the grout gap and clips must break at the right point, so size control matters even on a low-cost part. Points to check when selecting a machine:
- Clamp force for the full projected area of many cavities
- Even fill so every spacer arm has the same thickness
- Consistent wall at the clip break-off neck
- Hot or cold runner layout matched to cavity count
- Ejection that drops every small part clear before closing
- Stable melt when running regrind or recycled PP
Recommended Machine for Tile Spacers and Levelling Clips
Each spacer or clip is light, but a very high-cavity mould spreads a large projected area across the platen. Smaller spacer moulds suit the E Series (75-180 T). Big cavity fields, levelling clips with a wide base plate and moulds that need more platen space move to the H Series (120-350 T).

FAQs / Buyer Questions
Questions spacer and clip makers ask when planning a line.
Which Injection Moulding Machine Is Used to Make Tile Spacers?
For small spacer moulds, an E Series horizontal machine is common. Clip moulds and very high-cavity spacer tools, which spread across more of the platen, are usually placed on the H Series.How Is the Break-Off Point on a Levelling Clip Kept Consistent?
The clip breaks at a thin neck below the tile surface. If that neck varies between cavities, some clips snap early and others will not break. Balanced runners, steady holding pressure and even cooling keep the neck the same in every cavity.Can Recycled PP Be Used for Tile Spacers?
Recycled or regrind PP can be used for some spacers, since they are thrown away after tiling. Its melt flow changes from lot to lot, which shows up as short shots on thin arms and uneven break force on clips, so blends need checking.
Hot Runner or Cold Runner for a Spacer Mould?
A hot runner saves runner material and suits very high cavity counts, but the mould costs more. A cold runner is simpler and its runner can be reground. Either way, the layout must fill every cavity at the same time.Can Pratishna Recommend a Machine for My Tile Spacer or Clip?
Yes. Share the spacer or clip drawing or sample, material, part weight, number of cavities, runner type, mould size and daily output, and Pratishna Engineers will recommend a suitable machine.Does the Machine Suit Other Tiling and Fixing Parts Too?
Yes. Similar machines can mould wall plugs, cable clips and saddles, faucet aerators and small conduit fittings, subject to the mould.
