Yard or workshop manual equipments, suitable for extrusion welding of plastic materials; they can operate with 3mm, 4mm, 5mm rods of PE and PP. STARGUN machines are used for the fabrication of containing tanks, fume treatment towers, scrubbers, chemical hoods, aspiration systems, and for joining linings and geo-textiles. The SB series has been designed in compliance with the current safety norms and regulations, and it is composed of:
a mini extruder, operated by an electrical engine. A plastic rod shall be fed through the extruder feeding mouth, to bring material to the plasticization chamber;
a Teflon shoe, directly fixed on the extruder, from which the welding rod would be coming out. The shoe can feature different configurations, by simply rotating the lateral handle around the extruder body;
a self blowing system located inside the control box makes the machine independent from any external air - compressor, making it even more compact and handy;
a double control thermoregulator, guarantees a precision of ± 2° C from the set temperature. The machine is provided with a digital display, where is visualized both the extrusion and the pre-heating temperature;
a safety system blocks the engine till the minimum set temperature has been reached (cold-start system). If the temperature varies more than 10°C

The Kneader Extruder combines the efficiency of a double arm - sigma blade mixer with the convenience of an extrusion screw for the mixing and discharging of heavy viscous materials.
The Kneader Extruder includes a set of counter-rotating kneading blades and a discharge screw. The blades are mounted on a horizontal axis in a u-shaped trough. Below the blades in a seperate cavity is the discharge screw. During the mixing cycle the blades rotate toward each other while the mixing screw rotates in a reverse direction, constantly feeding new materials into the mixing blades. After the mixing/kneading cycle is complete, the screw is reversed and it transports the mixed materials from the mix zone out through a discharge die and on to further processing or packaging.
The Kneader Extruder has several advantages over conventional non-screw discharge kneaders:
1. Mixes in approx. 15% less time
2. Eliminates the manual task of scraping out sticky/tacky materials.
3.Eliminates operator exposure to materials of elevated temperatures or of a toxic nature, thereby improving plant safety.
Many sizes and designs are availble to meet the most stringent process needs. Kneader Extruders are manufactured in many sizes from 1 through 1000 gallons capacity.

Different processing lengths and screw geometries guarantee a wide area of application. Venting zones, interchangeable grooved bushes, stroke adjustment systems and many more features allow for an extremely versatile application in setting up extrusion lines.
As standard, all extruders are equipped with microprocessor control contained in a swing-out unit above the extruder.

Double shaft extruder gears have been built by PIV Drives since 1984 for a variety of applications in the plastics and food industries. This product is in operation around the world to the complete satisfaction of our customer base. The gearing is case hardened and ground with a profile correction for optimal load-bearing performance and noise reduction. An extremely quiet gear-train is achieved through a high contact ratio. The axial forces which occur during the extrusion process are safely absorbed through a system of tandem bearings and self-aligning roller thrust bearings.
Technical Data:
Screw centre distance: a = 15 up to 200 mm
Input speed: up to 1,800 rpm
Torque factor: df = 35 Nm/cm3
Power: up to 5,500 kW
