Main Component

• SJ45/25 extruder host:1 set
• U7 machine head:1 set
• 1.5m movable Stainless steel sink:1 set
• Control system:1 set

• Screw diameter: Ф45mm
• Length diameter ratio of screw: 25:1
• Screw type: high efficiency BM screw;
• Screw speed: 110R / min
• Glue output (max): PVC: 70kg / h;
• Main motor power: 11kw (AC), AC motor
• The screw material is 38CrMoAlA, the surface is nitrided,
•  the nitriding depth is 0.5-0.8mm, and the surface hardness is ≥ hv840
• The barrel material is 38CrMoAlA, the surface is nitrided,
•  the nitriding depth is 0.5-0.8mm, and the surface hardness is ≥ hv940 
•  The main motor is 11kw AC motor controlled 
• by Shenzhen sinusoidal frequency conversion speed regulation system.

• The temperature controller adopts the latest generation of digital touch products, and the temperature control accuracy is ± 2 ℃
• Number of temperature control sections (fuselage / nose): 3 / 2
• The fuselage adopts electric heating and fan section cooling.
• The machine head adopts Haff clamping, which is convenient to operate.
• The gear box is processed by hard tooth surface grinding process. All gears are quenched and tempered with 40Cr, the tooth surface is quenched and tempered with high frequency, the surface hardness is hrc50-55, and the shaft is quenched and tempered with 45# steel, hb133

•  Wire diameter range: Ф0.3～Ф7mm；
•  It is free of adjustment. The head is processed with high-quality die steel. The surface heat treatment is resistant to high temperature, corrosion, small coefficient of thermal expansion, high red hardness, and the concentricity of wire rod reaches more than 95%. The neck and head are heated by cast aluminum heater and cooled naturally. The thermocouple temperature control feedback is adjusted. The positive and negative teeth are ladder shaped thread adjustable Hafu clamping, and the outside of Hafu is heated by cast aluminum heater, Thermocouple temperature control feedback regulation
•  Equipped with a set of commissioning mould (mould core and mould sleeve)
• features: when replacing the mold core and mold sleeve, it is not necessary to remove the mold core rod. After adjusting the eccentricity at low speed, the concentricity remains unchanged when the speed increases to the normal production speed. The eccentricity is required to be less than 15%. After adjusting the machine at low speed and increasing the speed synchronously, the outer diameter deviation is within the standard tolerance of cable products.

•  Model: sub bus slot type.
• Structure: the main tank is of water tank type, and the sub tank is retractable, with a total length of about 1.5m.
• Material of tank body and water tank: 1.5mmt stainless steel plate
• Cooling method: room temperature soaking.

• Power supply: three-phase five wire system, 380V (± 10%), 50Hz, single-phase control voltage 220V
• The main machine and traction motor of the extruder are domestic brand AC motors controlled by Shenzhen Sinee frequency conversion speed regulation system. The latest generation of intelligent electronic display calculus temperature controller is selected as the temperature control instrument, and the temperature control accuracy is ± 2 ℃. The panel is equipped with various instruments, indicators, switches and other necessary components, with complete protection functions such as overload, overheating and overcurrent,
•  The low-voltage components of the whole machine adopt domestic top brands (Chint or Schneider), which has the advantages of stable starting, running and stopping of the production line, energy saving and consumption reduction.
• the control box is spliced by high-quality anodized aluminum profile and aluminum die-casting corner parts, with simple and stable appearance and simple operation. A dust filter device is installed in the main control box to prevent the service life of electrical components in the cabinet from being affected by dust.
• Measurement devices in software program：pressure , temperature ,  amperage.
