Vacuum forming signage is a common type of sign, widely used in sign making due to its advantages such as beautiful appearance during the day and bright evening, good weather resistance, and durability. The vacuum forming signage character signboard consists of three parts: an acrylic vacuum forming panel, a luminous character box, and a luminous character light source.

1. Attracting attention: vacuum forming signage breaks through traditional two-dimensional expression techniques, using three-dimensional shapes to activate people's spatial imagination, and has a strong sense of three-dimensional shape.
2. Various color:
3. High cost-effectiveness: balancing both day and night effects. Not easily deformed or faded.
4. Green and environmentally friendly: Due to the complete recycling and reuse of acrylic materials, it is considered a form of green advertising.
5. Good performance: It has good corrosion resistance, rain resistance, fire resistance, and self ignition resistance.
6. Long service life: with an average lifespan of 80000-100000 hours;
7. Energy conservation and environmental protection: The safety voltage of the lighting system inside the font is 12V, which does not pose any harm to personal safety. The entire product does not produce light pollution or chemical pollution during use.
8. Widely used: The vacuum forming signage are widely used in store advertisements and advertisements in shopping malls, hotels, parks, buildings, and various institutions.

**Preform Injection Molding Machine Specification**
**Model NO.:** BLIM-1700A
**Description:**
1. **Clamping Unit**
The BLIM-1700A features a five-point double toggle clamping unit with a novel negative rear angle design. It is engineered using finite-element analysis for optimal platen rigidity and durability. The machine offers a large opening stroke, allowing for the use of larger molds. An adjustable moving platen support system ensures stability when handling heavy molds. The programmable control system allows for multiple mold speed and pressure settings, enhancing flexibility and efficiency. A high-sensitive, low-pressure mold protection device and mold closing alarm are included for safety. The precision gear system enables accurate mold height adjustment and automatic mold alignment based on preset clamping pressure. Additional safety features include an electrical and mechanical interlock, and an automatic centralized lubrication system with oil-out alarms. The ejector system includes a delay timer, multi-stroke, and multi-vibrating functions for better performance.
2. **Injection System**
The injection system uses twin-hydraulic cylinders for fast and stable injection. The injection screw has a large L/D ratio of 20:1, ensuring efficient plasticizing. The screw and barrel are specially designed with nitrided steel to extend service life. A protective cover is included for operator safety. The built-in computer-monitored system ensures precise plasticizing. Features such as two-stage plasticizing, speed, pressure, and position control, along with programmable auto-purge, allow for quick color changes. The system also includes a hopper material empty alarm, programmable decompression, and adjustable back pressure control (zero back pressure available on TRX400). Precise temperature control and a nozzle centering device are also part of the system. Additional tools like a screw speed display and back pressure meter enhance usability.
3. **Hydraulic System**
The hydraulic system uses a dual proportion load induction circuit for steady operation and energy savings. High-quality components from reputable manufacturers are used for the motor, pump, valves, oil seals, and high-pressure hoses, ensuring reliability and performance.
4. **Control System**
The micro-processor controller system allows storage of mold data including time, pressure, speed, and stroke. A high-resolution LCD makes operation easier. All electrical components come from well-known manufacturers, ensuring long-term reliability. Linear transducers are used for injection, clamping, and ejection, while fuzzy temperature control improves accuracy.
