This series of extruders is a product independently developed by our company. It adopts a new model controlled by microcomputer PLC and has obtained a patent certificate issued by the National Patent Office. The main types of products applicable to various tonnage models are:

（1） VT-250T~350T extruder:

(1) Lead tin alloy wire (extrusion specification of φ 5- φ 16mm);

a、 Lead tin wire: can extrude lead tin alloy with lead content of 10-99.95%
b、 Squeezeable single core and three core rosin solder wire;
(2) Lead free solder wire (extruded specification of φ 5- φ 16mm)

a、 Tin copper lead-free solder wire;
b、 Tin silver lead-free solder wire;
c、 Tin silver copper lead-free solder wire, tin zinc lead-free solder wire (with Zn content not exceeding 25%);
d、 The above solder wires can be extruded into single core and three core rosin solder wires;

(3) Lead and lead-free tin bars (require cutting and coding machine)
（2） VT-500T extruder:

(1) Lead free solder wire (extruded specification of φ 5- φ 16mm)）

a. Tin copper lead-free solder wire;
b. Tin silver lead-free solder wire;
c. Tin silver copper lead-free solder wire tin;
d. The above solder wires can be extruded into single core and three core rosin solder wires;
e. Tin zinc alloy wire (with Zn content not exceeding 50%);

(2) Lead free anode rod (requires anode rod cutting machine):

This series of extruders consists of five main parts: mechanical system, hydraulic system, pneumatic system, heating system, and control system. It is one of the advanced horizontal extruders that our company has successfully absorbed advanced foreign technology and independently developed. It has the advantages of time-saving, labor-saving, low energy consumption, and stable performance. The main cylinder of the extruder adopts a plunger type composite mother and child oil cylinder structure, which successfully absorbs advanced hydraulic speed control technology from abroad and ensures the safety of the hydraulic system.

1Master cylinder:Adopting a plunger type hydraulic cylinder (German technology) with a working pressure error of 0.002KG, the hydraulic system has the characteristics of strong and powerful constant speed stability, ensuring the stability of metal and rosin flow extrusion.

2Built in sub cylinder:It has the functions of fast oil filling, reducing idle time, quickly reaching working pressure, and improving efficiency.

3、 Equipment features:

1. This extruder is controlled by a microcomputer PLC, and the requirements for product process parameters can be set and modified through a touch screen (human-machine interface) during operation,
Greatly improving the accuracy and automation of mechanical performance, with simple and convenient operation. The operation technician can store the process parameters of different products in the PLC through the touch screen. During operation, they only need to select the set production process category to automatically operate, solving the problem of training skilled craftsmen for enterprises.
2. The control circuit is DC24V, which is safer for both personnel and equipment.
3. The precision EC10-4TC module temperature control system is adopted to more accurately control the heating temperature required for production, with a temperature control error of only ± 10 ℃, thereby improving the stability of product quality. At the same time, four sets of timing switches can be set, which have the function of preheating in advance, so that employees can start working at any time when they go to work.
4. The microcomputer is equipped with automatic fault alarm and diagnosis functions. When mechanical faults occur, the root cause of the fault can be quickly identified through PLC, greatly reducing maintenance time and improving production efficiency.
5. Adopting imported programmable controllers makes mechanical operation more stable and has a long service life.
