Plastic pallet mainly has two kinds: plastic injection pallet and blow molding pallet
Blow molding pallet its strength is high, low temperature resistance good performance, superior quality, blow molding pallet service life is very long, some even can use for ten years.Because the intensity of this kind of pallet is higher, plastic pallet relative to injection molding plastic pallet price slant expensive, but its cost performance is the best.Blow molding pallet varieties are few, basically are two-sided pallet, mainly used in chemical industry and other industries, mainly used for stacking, blow molding pallet in recent years also developed a single-sided nine-foot can be stacked plastic pallet, widely used in the logistics industry, can be stacked, greatly save space, load-bearing than injection nine-foot pallet significantly improved.
Blow molding pallet molding process adopted by the blow molding equipment generally require relatively large blow molding machines, plastic extrusion blow molding, with PE production PE plastics by extrusion into tubular plastic parison, strike put in split cavity, mold closing immediately after pass into the compressed air in the plastic parison, make plastic parison swell and clingy wall in the mold, the cooling stereotypes demoulding, namely get all kinds of blow molding pallet.
At present, the volume of blow molding hollow container can reach thousands of liters, and the large hollow molding machine developed and manufactured in China has reached 2000L, which is controlled by computer.Production blow molding pallet generally can only use PE as raw material.Therefore blow molding pallet and injection molding plastic pallet product quality is the plastic pallet inside the quality level is the best.The ambient temperature can work stably under the condition of -40° C and the service life can reach 8~10 years.
Injection molding of plastic pallet in the use of value and blow molding pallet can be comparable to, due to the injection molding process on the price, the price on injection molding plastic pallet price comparison has the upper hand, injection plastic pallet product variety complete, size is diversiform, can be built-in steel tube, still has dominated the plastic pallet industry, the use of plastic pallet, can bring great benefits to logistics and other related industries.A product formed by a rapidly developing plastic processing method.
