A polyurethane forklift wheel is a cast PU tread bonded onto a steel or aluminium core. PU is chosen over rubber because it carries higher load, resists wear and chunking, rolls with less resistance…
PU insulation pipe shells are rigid polyurethane half-shells that clamp around pipework for district heating, chilled water, steam and process lines. Rigid PU is used because it has one of the lowest thermal conductivities…
Potting and encapsulation protect EV battery cells and modules from vibration, moisture and thermal runaway, and add structure to the pack. The part is produced by a two-component metering-mixing-dispensing (or foaming) machine. As a…
Getting heat out of an EV battery pack depends on the thermal interface between the cells and the cooling plate. Two options dominate: pre-cut thermal gap pads, and liquid-dispensed thermal gap fillers. For volume…
Moulded polyurethane foam is the standard for automotive, motorcycle and furniture seat cushions. The key equipment decision is whether to run a high-pressure or a low-pressure foaming machine. As a manufacturer of both, we…
Choosing the right insulation core is the single biggest decision in cold storage and cold-room construction. The three common options — rigid polyurethane (PU), polyisocyanurate (PIR) and expanded polystyrene (EPS) — differ sharply in…
How elastomer casting machines dose, mix and pour PU systems. Compare low- vs high-pressure metering, key specs and selection criteria for B2B buyers.
How a PU dispensing system works, high-pressure vs low-pressure metering, key specs, and how to match a polyurethane dispensing machine to your line.
Electric-vehicle battery packs rely on several polyurethane (PU) parts for thermal management and protection: cell and module encapsulation foam, potting compounds, thermally conductive gap fillers and pack-housing gaskets. Yongjia builds the high- and low-pressure…
A technical breakdown of the basic parts of a refrigerator, from the compressor to the PU foam cabinet, and how foaming machines build the insulation core.
A practical PU machine buyer's guide covering low- and high-pressure foaming machines, key specs, output ranges and selection criteria for B2B manufacturers.
A practical guide to choosing a polyurethane machine: high vs low pressure metering, mixing accuracy, output range, mold matching and ROI for PU production.
