Yiyongli is a leading supplier of custom plastic large part by vacuum forming process across a variety of industries.We can provide product design and manufacturing engineering assistance and is ISO 9001:2015 registered.
Vacuum forming is a very economical method for producing large plastic parts.It offers lower cost tooling and quicker prototyping than other technology. Vacuum forming is best choice compared to other manufacturing methods such as complex fabricated sheet metal or fiberglass, in large, complex shapes which require a lot of metal fabrication, grinding and finishing. Vacuum forming also compares favorably to injection mould in big plastic parts when small quantities.
Vacuum forming large parts are single component parts that come out of the actual product or a substantial part of the finished product. Usually they are enclosures or housings for equipment.Applications of vacuum forming large parts are seen in many industries, including medical equipment panels ,machine enclosures, engine covers for aerospace, transportation or construction industries, and rail-car interior trim or seat components.

Positioning system to ensure the correct installation of hydraulic valves and hoses
Caterpillar, the world's maker of construction machinery, relies on a real-time positioning system at a heavy equipment factory in Belgium to ensure the correct installation of hydraulic valves and hoses. When workers assemble hydraulic valves at the Caterpillar Belgium factory, they use tweezers to tighten the conduit (made of rubber and steel) to the valve. Valves - Installed on construction vehicles made by Caterpillar - the size of a car engine. To secure the catheter to the valve and to ensure proper valve operation, the worker must tighten the bolt with a specified amount of torque - about 300 Nm. Before using the RFID system, workers had been tightening the bolts manually with a tweezers and could not confirm that the torque reached the correct Newton meters. Caterpillar used the Protrac, a software system provided by DeJaeger Automation, a Belgian industrial software company, on the assembly line to track the assembly and corresponding staffing and assembly time for each part. The worker enters his ID code and details of the work to be performed on the software running on the container station PC, as well as the serial number of the planned installation component. Before using RFID, the tightness of the catheter installation can only be determined by the staff's judgment. The employee painted the part with the marking of the pigment and the visual connection closely. The factory has about 4,300 worker rotor pumps built for medium and large excavators and wheel loaders. Caterpillar and DeJaeger met in 2008, Caterpillar project manager Degraux said the two companies decided to work together to develop a cost-effective RFID system. In December 2008, DeJaeger installed RFID readers in the main Caterpillar high-pressure hydraulic valve assembly area. The RFID system works with Protrac software. In the meantime, the company replaced the manual torsion pliers with 6 sets of electronic torsion pliers with active RFID tags. Each wrench is designed for a specific packing area and is preset for a specific torque. When the worker reaches the maximum valve preset force, the wrench starts ticking, indicating that the catheter is properly installed and the applied torque is transmitted to the corresponding PC. By applying RFID tags on each wrench, the real-time positioning system ensures that the correct wrench is used at the correct location. More Keyword Search: Hydraulic Valve
