Injection moulding machines, extruders, blow moulding and film plants run hot hydraulics and heavily loaded gearboxes around the clock. Oil condition often decides whether a shot is good or scrap.
Plastics processing is hydraulics-intensive. A conventional injection moulding machine holds a large volume of hydraulic oil that cycles every few seconds through clamping, injection and ejection, often in a hot shop. Extruders drive their screws through heavily loaded thrust bearings and gearboxes. Barrel heaters, hot moulds and hot oil all speed up oxidation. Clean, cool, correct-grade hydraulic oil is the biggest single lubrication factor in a moulding shop.
Banesto supplies anti-wear hydraulic oils, EP and synthetic gear oils for extruder gearboxes, high-temperature and long-life greases, and Beltone belts for granulators, blowers and auxiliary drives.
Selected from our 852+ SKU range for the duty cycles most common in plastics processing plants. Every recommendation is matched by application (temperature, load, speed and exposure), not by catalogue number. Where the equipment maker specifies a grade, the maker's specification comes first.

| Equipment | Lubrication point | Banesto product | Good practice |
|---|---|---|---|
| Injection moulding machines | Hydraulic tank | Hydraulic Oil HLP 46; HLP 68 if specified | Keep the oil cooler working and the oil within the maker's range, typically 40–55 °C. |
| Injection moulding machines | Toggle pins, bushes, platen guides | Lithium Complex MP or the maker's specified lubricant | Check the automatic lubricator every shift. |
| Extruders | Gearbox and thrust bearing | Industrial Gear Oil or PAO Synthetic Gear Oil, grade as per the maker | Check the oil cooler and oil temperature daily. |
| Blow moulding and film plants | Hydraulics, gearboxes | Hydraulic Oil HLP 46; Industrial Gear Oil | Filter new oil when filling. |
| Granulators, blowers, chillers | Belt drives | Beltone wedge and classical belts | Replace belts as a matched set. |
| Motors | Bearings | Polyurea Bearing Grease | Do not over-grease electric motors. |
| Air compressors | Crankcase | Compressor Oil ISO VG 100 (reciprocating) | Drain condensate daily. |
Most use an anti-wear mineral hydraulic oil of ISO VG 46 (HLP 46 or HM 46); some makers specify VG 68 for hot shops or heavily loaded machines. Use the grade in the machine manual.
Common causes are a blocked or undersized oil cooler, low oil level, internal leakage in worn pumps or valves, and the wrong viscosity. Our hydraulic oil overheating guide explains each.
Servo and proportional valves often need oil at ISO 4406 16/14/11 or cleaner; check the valve maker's figure. Filter new oil when filling, because new oil is not always clean enough. See our ISO 4406 guide.
Typically an EP industrial gear oil of ISO VG 220 or 320, as the gearbox maker specifies. Synthetic PAO gear oil runs cooler and lasts longer in hot, continuously loaded gearboxes.
