Material of Screw: One Ø120mm screw with whole tooth nitrogen

treatment of alloy steel and chrome-plated polished surface and screw-passing cooling water device.

Material of Screw Cylinder: 38CrMoA1A alloy steel, nitrogen treatment and precisely grinding. The surface hardness inside the screw cylinder is R2-3 degree higher than that of the front surface of the screw and the screw thread. The cooling water jacket is added on the feed point of the screw cylinder.

Gearbox: Imitation of Italian-type, hardened helical gear gearbox, material of cast steel, oil-bath lubrication, tooth-face high-efficiency quenching and adoption of Japanese NACHI bearing.

Electric Heating: 380V, with even three-phase separated flow.

Screw cylinder electric heating zone 6, the cast aluminum heating ring heating is affixed with cooling air duct.

Head electric heating zone 1, heating by cast aluminum heating ring.

Neck electric zone 1, heating by the electro-thermal tablets.

Eye die electric heating zone 1, heating by the electro-thermal tablets.

Control of Temperature: Use the PID automatic temperature control gauge made in Yangming, Taiwan, automatically set the control under 0-399℃ and use KTYP as the thermal-couple.

Cooling: Screw cylinder zone 6, use 6 sets of cooling fans (550W).

Head: Right-angle adjustable eccentric head.

Host Motor: The motor drags with 90 KW. The inverter controls and unloads by synchronization. The velocity adjustment is convenient and steadily operated.
