The complete STAR 300S line was developed for the most demanding footwear makers. Soles, insoles, direct injection onto the upper, safety or fashion footwear: precision, flexibility and robustness to raise your quality and productivity.
STAR 300S-PV Patent pending Line highlights
Latest-generation PLCs and a 10″ touchscreen HMI: pressures, temperatures and shot times in real time, with recipe storage and recall. Faster set-up and reliable operation.
Dual heads and turbine-type mixers ensure homogeneous mixing in two-component and multi-colour processes, with polyether or polyester. Electric motors and gear pumps deliver precise output — up to 7 kg/min at a 1:1 ratio.
2, 3 or 4 fully sealed carbon-steel tanks with thermal-oil circulation heating for material stability. A compact, epoxy-painted structure that is easy to maintain and built to last.
Automated or manual cleaning, with pressurisable stainless-steel tanks, to keep production running with fast, safe maintenance.
6-station modules configurable up to 36 stations, and rotary carousels in indexing or continuous mode, to optimise workflow and moulding cycle.
Featured · Automated solution
Configured with 24, 36 or more stations, one or two automatic injection carriages and dual or single heads, the STAR 300S-R can exceed 500 pairs per hour — and reach 700 with optimisation.
Models
The whole line is STAR 300S. The suffix defines the model — and each one solves a production need.
Automated High-volume safety soles with direct injection onto the upper.
Sulpol’s automated solution for safety-footwear soles by direct injection onto the upper. It can be configured with 24, 36 or more stations and run one or two automatic injection carriages, with dual or single heads.
Patent pending Double closing that removes manual handling of the first cavity.
An innovative machine for footwear, with a double-closing mould-carrier system (patent pending) that removes manual handling of the first cavity. With two heads and two operating arms, it delivers high output, safety and precision in PU soles and insoles.
Classic The versatile model for direct injection, soles and insoles.
The classic, versatile model for direct injection onto the upper, soles and insoles in polyester or polyether PU, single or dual density. Mould options from 6 to 36 stations and up to 5 colours.
Semi-automated A 36-station rotary carousel with one or two processors.
A semi-automated rotary machine with a 36-station carousel (or configured to need), built with one or two processors. Ideal for polyester or polyether PU soles and insoles, single or dual density.
Continuous rotation Semi-automatic, with a continuous-rotation carousel for flow production.
A semi-automatic machine with a continuous-rotation carousel: stations pass the dosing point without stopping the carousel, keeping production flowing. STAR 300S metering unit and a carousel with perimeter guarding. Stations, densities and colours are configured with Sulpol engineering.
Rotating tower Rotating tower and up to 5 colours for direct injection, soles and insoles.
For direct dosing onto the upper, soles and insoles in polyester or polyether PU, single or dual density. Mould carriers on a rotating tower from 6 to 36 stations and a 1 to 5 colour range.
Double arm Two arms, one metering head on each: high output for safety and fashion footwear.
For high-volume safety or fashion footwear with direct dosing onto the upper, single or dual density, with two arms and one metering head on each. Also produces polyester or polyether PU soles and insoles, with a 36-station rotating tower and a 1 to 5 colour range.
