In recent years, the rise of cold-chain logistics is the gradual growth of the refrigerated car market. Difficulties in market demand will cause some unscrupulous enterprises to oppose the speculation. It is a repertoire for the refrigerated truck market, which will undoubtedly increase the difficulty of purchase. Let's introduce to you today how to choose a cost-effective refrigerated truck . The performance of refrigerated trucks is mainly reflected in the chassis, the insulation compartment, and the refrigerator. A good refrigerated truck must have the best performance in these three core areas. First of all, the choice of chassis should be decided according to the amount of transported goods and the transport distance. The short-distance transport chooses the chassis of light trucks, and the heavy-duty medium-to-long-distance transport for heavy-duty trucks is to choose the chassis of heavy-duty trucks or traction semi-trailers. Some users tend to choose the import chassis when choosing, and the imported chassis is often better than the domestic chassis in performance, but its price is also much more expensive. In fact, in recent years, the performance of domestic chassis has been constantly optimized, and the quality is constantly improving. Therefore, the owner can make rational choices based on his own economic ability. Secondly, the car body can be customized according to the needs of the user. For example, a refrigerated car that can be opened more often is designed to facilitate frequent loading and unloading of goods. Configuring some small components in the refrigerated box can meet the needs of special cargo transportation, making transportation more convenient and quick. This is also a humanized aspect in the design and production of refrigerated trucks. Finally, the refrigerant can be said to be the soul of a refrigerated truck. Refrigerants are divided into non-independent units and independent refrigeration units. The non-independent refrigeration units are inexpensive and easy to repair, so they can be applied to short-distance distribution; independent refrigeration units can continue to work in the event of a car engine failure, to meet the safety of goods, and are therefore used for long distances. transport. In the use of refrigerated trucks according to different transport conditions, there should be strict requirements, users should fully consider their own needs when buying refrigerated trucks , do not only consider the price factor, cool and rational choice of an environmentally friendly, comfortable, cost-effective refrigerated truck .
Copper die casting part is similar the aluminum die casting, the die casting machine also the same, but the life of Cu Die Casting Mould is very short, only about 10,000 shots, because the high melting point of copper alloy, it is easy make the mould aging.
