When to choose the PLATEX 185
The PLATEX 185 by Takımsan is the entry into the high-throughput tier of the PLATEX series. With a 90 kW extruder motor and 750–1,500 kg/hr capacity range, it targets production operations that have outgrown the PR 150 gearbox family’s upper limit or need PR 250 torque reserve for demanding compound classes.
The PLATEX 185 offers a configuration choice not available in the 155 or 165: dual gearbox compatibility. Specified with the PR 250 gearbox (1/19 ratio), it handles sustained throughput above 1,200 kg/hr on high-viscosity or heavily filled formulations — the target segment for PVC pipe compound producers running 24-hour shifts. Specified with the PR 150 gearbox (1/16 ratio), capital cost is reduced for operations where the full PR 250 torque margin is not required, such as masterbatch or standard PVC window compound at 750–900 kg/hr. Takımsan specifies the correct configuration based on the compound data sheet and throughput target.
A typical PLATEX 185 customer is a scaling rigid PVC or WPC compound producer: a facility that started with one or two PLATEX 155 or 165 units and now needs a single high-throughput compounding line to serve a larger downstream extrusion park, or a greenfield investment where 1,000+ kg/hr is the design target from day one.
Comparing to adjacent models: The PLATEX 165 (600–1,100 kg/hr, 75 kW, PR 150) is appropriate when throughput targets are reliably below 900–1,000 kg/hr on standard formulations. The PLATEX 200 (850–1,800 kg/hr, 110 kW) delivers higher top-end capacity through a larger barrel diameter — the correct step if sustained output above 1,500 kg/hr is required. The PLATEX 185 is the right specification in the 750–1,500 kg/hr range, particularly where PR 250 gearbox flexibility across formulations matters.
Materials and applications
Rigid PVC in high-volume pipe and profile compound lines. At 1,000 kg/hr on standard 25 phr CaCO3-filled rigid PVC, the PR 250-configured PLATEX 185 operates well within its torque envelope. Formulations up to 50 phr CaCO3 are within range. For detailed process guidance, see rigid PVC compounding.
Soft PVC for high-volume cable insulation compound and automotive interior applications. At these throughput levels, melt temperature control is especially important — the planetary roller geometry maintains the melt film below PVC degradation thresholds without active compound cooling.
PE + CaCO3 at high loading: polyethylene filled to 60% by weight. The 90 kW motor provides torque reserve for heavily loaded grades at sustained production rates without the cyclic torque peaks that limit single-screw operation.
WPC: wood flour at 50–65% by weight with PE or PP. Stage 2 vacuum degassing removes moisture at high throughput rates; Takımsan engineers the degassing section residence time to match the commissioned throughput target.
Colour masterbatch: high-throughput pigment concentrate production for large-volume industrial customers.
Plastic recycling: post-consumer polyolefin and PVC blends at industrial scale, where variable feedstock quality and moisture content make vacuum degassing essential.
Power consumption economics
At 1,000 kg/hr throughput on a rigid filled PVC compound (approximately 25 phr CaCO3), the PLATEX 185 with PR 250 gearbox draws approximately 60–68 kW from the 90 kW extruder motor. Total power including discharge motor, vacuum system, and auxiliaries: approximately 105–115 kW. This is an estimate; actual draw depends on formulation, barrel temperature profile, and gearbox configuration.
Over a 6,000-hour operating year (two shifts, approximately 250 days), at an average throughput of 1,000 kg/hr:
- PLATEX 185 electrical consumption: approximately 630,000–690,000 kWh
- At €0.10/kWh: approximately €63,000–69,000/year
A co-rotating twin-screw compounder at equivalent 1,000 kg/hr throughput on rigid PVC typically requires 90–100 kW main drive. At 6,000 hours, approximately 15–20% higher electrical consumption — approximately €9,000–15,000/year more in energy cost than the PLATEX 185 at equivalent throughput (estimated).
At 1,000–1,500 kg/hr production scale, the absolute energy cost difference between planetary roller and twin-screw processing becomes a material line item in the annual operating budget.
Why PLATEX 185 over alternatives
vs. European-manufactured planetary roller extruders in this capacity tier: The processing principle is identical: same helical planetary roller geometry, same 45° helix angle, same vacuum degassing stage design. ISO 9001:2015 certification and CE marking document an equivalent quality management standard. Total cost of ownership for PLATEX by Takımsan is typically 30–50% lower than a comparable European planetary extruder specification at this capacity tier (estimated). For operations that need planetary roller processing quality at high throughput, the PLATEX 185 is the direct alternative.
vs. large co-rotating twin screw: At 1,000+ kg/hr on rigid PVC, large co-rotating twin screws deliver reliable throughput but require higher motor ratings and generate higher melt temperatures in filled formulations. The PLATEX 185’s planetary geometry maintains 8–15°C lower melt temperature at equivalent throughput (estimated), which directly affects long-term colour stability in UV-stabilised window profile compound.
vs. operating two smaller PLATEX units: Two PLATEX 155 units each at 500 kg/hr provide equivalent throughput to one PLATEX 185 at 1,000 kg/hr, but require double the operator attention, double the startup/shutdown cycles, and double the number of gearbox and roller sets in the maintenance schedule. For a dedicated high-throughput line, one PLATEX 185 is the simpler and more cost-effective operation.
