Every injection moulding machine in your plant — whether it is a 50-tonne horizontal press running PET bottle preforms or a 2,000-tonne machine closing on a large automotive bumper tool — runs on hydraulic power. The hydraulic system controls clamping force, injection pressure, holding pressure, ejection, and core pulls simultaneously, often at pressures between 160 and 280 bar, cycling hundreds of times per shift. The hydraulic oil inside that system is not just a fluid. It is the power transmission medium, the pump lubricant, the valve actuation fluid, and the heat transfer agent — all at the same time.
Get the hydraulic oil wrong, and you will see it within months: sticky proportional valves that cause pressure inconsistency from shot to shot, servo valve spool sticking that destroys repeatability in servo-electric-hybrid machines, pump wear that announces itself as increased noise and then fails at the worst possible moment, and seal degradation that means you spend Saturdays fixing hydraulic leaks instead of running production.
Imperiea Engineering & Sourcing Pvt. Ltd. is an authorised GS Caltex distributor in Pune, supplying Kixx Hydro XW — the hydraulic oil most widely specified for high-pressure industrial and injection moulding applications — to plastic processors, auto-component moulders, and packaging manufacturers across Pune, PCMC, Chakan MIDC, Talegaon, and Maharashtra.
What Injection Moulding Machines Actually Demand from Hydraulic Oil
This is where most generic hydraulic oil guides fall short. They list properties like ‘anti-wear’ and ‘oxidation stability’ without explaining why those properties matter specifically for injection moulding. Let me be more precise.
High-Pressure Pump Protection at 250+ Bar
The axial piston pumps and vane pumps in modern injection moulding machines operate at significantly higher pressures than most industrial hydraulic systems. At 250 bar on a 500-tonne machine, the specific loading on pump components is extreme. A hydraulic oil that meets the standard anti-wear specification for general industrial use may not provide adequate film strength at these pressures. The stabilised zinc dithiophosphate (ZDDP) additive system in Kixx Hydro XW is calibrated for exactly this load range — the zinc chemistry forms a sacrificial anti-wear film on metal surfaces under high contact stress, preventing the micro-welding and surface fatigue that degrades pumps prematurely.
Servo Valve and Proportional Valve Cleanliness
Modern injection moulding machines — particularly servo-hydraulic and hybrid models from manufacturers like Engel, Arburg, Haitian, and KraussMaffei — use proportional directional control valves and servo valves with spool clearances of 4–8 microns. At that clearance, a 15-micron particle is large enough to cause stiction. The ISO cleanliness requirement for servo valve hydraulic circuits is typically ISO 4406 code 15/13/10 or cleaner. Hydraulic oil with poor filterability — oil that tends to form soft deposits or gel particles at temperature — makes maintaining that cleanliness extremely difficult even with good filtration. Kixx Hydro XW is formulated with excellent filterability as a design parameter, not an afterthought.
Thermal Stability Across Long Shift Cycles
An injection moulding machine running a 24-second cycle for 16 hours continuously generates substantial heat in the hydraulic oil — from pump inefficiency, proportional valve pressure drops, and the work of compression at high pressure. Most plants control oil temperature with a water-cooled heat exchanger, but the oil temperature still cycles between 40°C and 55°C under normal operation, and can spike to 65°C or above if the cooler is undersized or scaling has reduced its efficiency. Oil that oxidises readily at elevated temperatures forms varnish deposits on servo valve spools, proportional valve bore surfaces, and hydraulic cylinder walls — leading to the sticking and drag that costs you cycle time and quality. Kixx Hydro XW’s thermal and oxidation stability is a primary formulation target.

Which Kixx Hydro XW Grade for Your Injection Moulding Machine?
This is the most common question we get at Imperiea. The grade selection for injection moulding hydraulic oil is not simply ‘use VG 46’ — it depends on three variables: your machine’s maximum system pressure, the typical oil temperature in your plant, and your machine OEM’s specification.
| Grade | Your Machine Scenario | Operating Temp | Typical Moulding Application |
| Kixx Hydro XW 32 | High-speed, light-tonnage machines (50–200T) Cool plant environment Light hydraulic circuits | 35°C – 50°C | High-speed packaging moulding, thin-wall moulding, precision multi-cavity tools |
| Kixx Hydro XW 46 | General injection moulding machines (100–800T) Standard Indian ambient temperature Most common grade | 40°C – 55°C | Auto component moulding, general plastics, FMCG packaging, consumer goods — the most widely used grade in Pune plants |
| Kixx Hydro XW 68 | High-tonnage presses (500–2000T) High ambient temp / poor cooling High-pressure circuits (>250 bar) | 50°C – 65°C | Large automotive structural parts, bumpers, dashboards; machines in hot plant environments or with inadequate oil cooling |
| Kixx Hydro XW 100 | Very large tonnage or specialty press Extremely high ambient (>40°C ambient) OEM specifically requires VG 100 | 55°C – 70°C | Specialist large tonnage presses; heavy-wall mouldings; consult OEM manual before selecting |
| Rule of thumb for Pune’s climate: VG 46 for air-conditioned or well-ventilated moulding shops. VG 68 for hot, poorly ventilated shops or machines regularly running at high duty cycle with oil temperatures consistently above 55°C. Always cross-check with your machine OEM manual — it specifies the hydraulic oil viscosity grade and the performance standard the oil must meet. |
Why OEM Approval Lists Matter — and What Kixx Hydro XW Covers
A lot of plant engineers in Pune ask whether OEM approvals really matter for hydraulic oil. The answer is: they matter significantly in two situations — when the machine is under warranty, and when you are running hydraulic components where pump rebuild cost is high enough to justify specification compliance.
Bosch Rexroth, Parker Denison, and Eaton/Vickers are the three hydraulic pump and valve manufacturers whose hardware appears in the majority of injection moulding machines used in India. All three publish approved hydraulic fluid lists, and all three specify the performance standard the oil must meet. Kixx Hydro XW carries approvals from all three:
- Bosch Rexroth RDE 90245 — the approval standard used for Rexroth axial piston pumps (A4VSO, A10VSO series), proportional valves, and servo valves used extensively in European and Korean IMMs
- Parker Denison HF-0, HF-1, HF-2 — Parker Denison’s tiered approval covering their piston and vane pumps used in a wide range of IMMs
- Eaton E-FDGN-TB002-E and M-2950-S / Vickers I-286-S3 — Eaton-Vickers pump approvals covering their widely used vane pump range
- Fives Cincinnati Machine P68/P69/P70 — covers machine tool applications where the same hydraulic fluid lubricates both the hydraulic system and the machine tool way-lube circuits
Using an oil that carries these approvals means you are not guessing at compatibility. The pump and valve manufacturer has tested the fluid in their hardware and confirmed acceptable wear performance. Using an unapproved oil does not guarantee failure, but it removes the engineering certainty that comes with a validated specification.

Performance Benefits of Kixx Hydro XW in Injection Moulding Machines
- Consistent shot weight and cavity pressure: stable viscosity means consistent hydraulic response cycle after cycle — reducing shot weight variation and improving first-pass quality rates
- Extended pump service life: the stabilised zinc antiwear system protects pump components against abrasive and adhesive wear at the high contact stresses of 250+ bar operation
- Cleaner servo and proportional valves: excellent oxidation stability reduces varnish formation on spool lands — maintaining valve response time and pressure control precision
- Longer oil drain intervals: thermal and oxidation stability that outlasts conventional anti-wear oils in the same operating conditions — reducing planned maintenance downtime
- Seal compatibility: formulated to be compatible with the nitrile, polyurethane, and PTFE seals used in standard hydraulic cylinders and accumulators
- Good air release and foam suppression: prevents micro-foam in the hydraulic oil that causes spongy, inconsistent hydraulic response — a common complaint in high-cycle injection moulding

Q: Can I use Kixx Hydro XW as a direct replacement for Castrol Hyspin AWS 46 in my injection moulding machine?
A: Yes. Kixx Hydro XW 46 and Castrol Hyspin AWS 46 both meet ISO 11158 HM, DIN 51524 Part 2 HLP, and Bosch Rexroth RDE 90245 specifications. They are functionally equivalent grades from competing manufacturers. Before switching, drain the existing oil fully and top up with Kixx Hydro XW — do not blend the two products in the same tank as mixing hydraulic oils from different manufacturers, even if specification-equivalent, is not recommended practice.
Q: How often should I change hydraulic oil in my injection moulding machine?
A: The first oil change in a new machine or after a fresh fill should be at 500–1,000 operating hours (typically 3–6 months for a two-shift operation) to remove running-in particles and initial contamination. Subsequent changes: for Kixx Hydro XW used in a well-maintained system with good filtration, 2,000–4,000 hours or 12–18 months is typical. Annual oil testing (viscosity, acid number, water content, particle count) is the best way to extend drain intervals with confidence.
Q: What ISO cleanliness level should my injection moulding machine hydraulic oil maintain?
A: For servo-hydraulic machines with proportional valves: ISO 4406 code 16/14/11 or better. For machines with servo valves: 15/13/10 or better. For standard hydraulic machines without proportional controls: 18/16/13 is generally acceptable. Kixx Hydro XW’s excellent filterability supports achieving and maintaining these cleanliness levels with standard return-line and pressure-line filtration.
Q: Is Kixx Hydro XW suitable for the hydraulic power pack of a two-platen IMM?
A: Yes. Two-platen machines typically run higher clamping pressures and larger hydraulic volumes than three-platen machines of equivalent tonnage. Kixx Hydro XW 46 or 68 (depending on operating temperature) is suitable for both two-platen and three-platen injection moulding machine hydraulic systems.
Q: How do I get Kixx Hydro XW delivered to my plant in Chakan MIDC?
A: Imperiea Engineering delivers from our Talawade warehouse to Chakan MIDC in approximately 1–2 working days. For plants with regular monthly consumption, we can schedule a fixed delivery date. Call +91 880 678 5151 with your Chakan MIDC plant address and requirement.
