2. Description: This series extruder is our self-developed products, using the number of explicit conventional models, has obtained national patent office issued a patent certificate, the model is mainly applied to the tonnage of product types are: (A) VT-250T ~ 350T extrusion machine: (1) pewter wire (extrusion specifications φ5-φ16mm) a, solder wire: can be extruded lead 10-99.95% of pewter wire b, can be extruded single and three rosin core solder wire (2) Lead free solder wire (extrusion grades φ5-φ16mm) a, Sn-Cu lead-free solder wire b, tin-silver lead-free solder wire c, tin-silver-copper-lead-free solder lead-free solder tin and zinc (Zn-containing not more than 25%) d, above solder wire can be squeezed into a single and three other rosin core solder wire (3) with lead-free solder bar (must be configured to cut coder) (Two) VT-500T extrusion machine: (1) Lead-Free Solder (extrusion grades φ5-φ16mm) a. Sn-Cu lead-free solder wire b. tin-silver lead-free solder wire c. SnAgCu lead-free solder tin d. above solder can be squeezed into a single and three other rosin core solder wire e. tin-zinc alloy wire (Zn-containing not more than 50%) (2) Lead anodes (anode rod cutting machine must be configured) This series of extruders by the mechanical systems, hydraulic systems, pneumatic systems, heating systems, control systems of five parts. Division I is successful absorption of foreign advanced technology, independent research and development of an advanced horizontal extrusion machine, with saving time, effort, low energy consumption, stable performance. Extruder master cylinder piston composite picture using the cylinder structure, the successful absorption of foreign advanced hydraulic speed control technology to protect the security of the hydraulic system. 1, using the ram cylinder (German technology), working pressure error (0.002KG) with constant speed and stability characteristics powerful hydraulic system to safeguard the liquidity squeeze metals and rosin stability. 2, the sub-cylinder: a quick oil-filled, reducing load time and quick to work pressure, improve efficiency of the function. Third, the device features: 1. The extruder adopt digital control, the digital meter installed in the console and press on the control panel, through direct control table for each set and modified to meet the requirements of process parameters on the product, simple operation, intuitive and convenient. 2. Control loop is DC24V, for persons and equipment more secure. 3. The use of sophisticated Japanese RKC temperature controller, more precise control of the heating temperature needed for the production, temperature error of only ± 10 ℃, thus improving the stability of product quality, while the timer switch can be set to four groups, with early pre- heating function, so that employees can work at any time to work.
