Polyurethane Front Driver Side Bucket Seat Bottom Lower Cushion Pad Molding Machine
Polyurethane provides comfort, safety and savings in car seats. Seats are required to offer more than ergonomics and cushioning. The seats manufactured from flexible moulded polyurethane foam cover these basic needs and also provide comfort, passive safety and fuel economy.
The car seat cushion base can be made both by high pressure (100-150 bar) and low pressure machines.
Polyurethane foaming machines are divided into high-pressure polyurethane foaming machines and low-pressure polyurethane foaming machines.
Different industries can use different types of foaming machines for foaming size requirements.
Features of polyurethane low pressure foaming machine:
1. The overall design adopts computer operation, even workers who are not good at using computers can operate in a few easy steps, with accurate data and high practicability.
2. The mixing head uses a new type of injection valve. The mixing head needs to mix a variety of raw materials. Even mixing is the basic requirement for the mixing head. The mixing head of the polyurethane low-pressure foaming machine spit out accurately and synchronously, without clogging and mixing evenly.
3. The metering pump has high precision. The metering pump is a meter for measuring various ingredients, and the accuracy of the ingredients affects the effect of product processing. The high-precision metering pump has a wide adjustment range, which can meet various needs of customers.
4. High-quality insulation material barrel. The material barrel must have heat preservation performance. Otherwise, the ingredients will solidify, affect processing, and damage the polyurethane low-pressure foaming machine equipment.

The basic function of the seat is to provide passengers comfort both in static and in dynamic conditions.
Static sense requires high resilience with surface smoothness and good firmness to heavy weights.
However, dynamic comfort can be considered as the key element. The ability to perform all flexible polyurethane foams to suit specific dynamic demands is, therefore, a significant advantage of this material.

Polyurethane Table Edge Banding Machine
The full name is polyurethane. A polymer compound. It was made by O. Bayer in 1937. Polyurethane has two types: polyester type and polyether type. They can be made of polyurethane plastics (mainly foam plastics), polyurethane fibers (known as spandex in China), polyurethane rubber and elastomers. Soft polyurethane (PU) mainly has a thermoplastic linear structure, which has better stability, chemical resistance, resilience and mechanical properties than PVC foam materials, and has less compre...
