吹塑成型的托盤其強(qiáng)度高，耐低溫性能好，質(zhì)量優(yōu)越，吹塑托盤的使用期限很長，有的甚可以使用十年的時間。因?yàn)檫@種托盤的強(qiáng)度比較高，塑料托盤上相對注塑塑料托盤偏貴，但是它的性價比卻是更好的。吹塑托盤品種較少，基本都是雙面托盤，主要應(yīng)用于化工等行業(yè)，主要用于堆碼使用，吹塑托盤近幾年也研發(fā)出了單面九腳可套疊塑料托盤，廣泛用于物流行業(yè)，可套疊，大大節(jié)約空間，承重比注塑九腳托盤大幅提高。
Blow molded pallets have high strength, good low temperature resistance and superior quality. The service life of blow molded pallets is very long, and some can even be used for ten years. Because the strength of this tray is relatively high, the price of plastic tray is relatively expensive compared with injection molded plastic tray, but its cost performance is the best. There are few varieties of blow molding pallets, basically double-sided pallets, which are mainly used in chemical industry and other industries, mainly for stacking. In recent years, blow molding pallets have also developed single-sided nine foot stackable plastic pallets, which are widely used in logistics industry, can be stackable, greatly saving space, and the load-bearing is significantly higher than that of injection molding nine foot pallets.
吹塑托盤成型工藝所采用的吹塑設(shè)備一般均需要較為大型的中空成型機(jī)，采用PE塑料擠出一次吹塑成型，生產(chǎn)時將PE塑料經(jīng)擠出成管狀塑料型坯，趁熱置于對開模中，閉模后立即在塑料型坯內(nèi)通入壓縮空氣，使塑料型坯吹脹而緊貼在模具內(nèi)壁上，經(jīng)冷卻定型脫模，即得到各種規(guī)格的吹塑托盤。
The blow molding equipment used in the blow molding tray molding process generally requires a relatively large hollow molding machine, which uses PE plastic extrusion for one-time blow molding. During production, PE plastic is extruded into tubular plastic parison, which is placed in the split mold while hot. After the mold is closed, compressed air is immediately introduced into the plastic parison to make the plastic parison expand and cling to the inner wall of the mold, which is cooled, shaped and demoulded, That is, various specifications of blow molding trays are obtained.
目前吹塑中空容器的體積可達(dá)數(shù)千升，國內(nèi)已經(jīng)研發(fā)制造的大型中空成型機(jī)已經(jīng)達(dá)到2000L，設(shè)備采用了計算機(jī)控制。生產(chǎn)吹塑托盤一般只能采用PE為原料。因此吹塑托盤和注塑塑料托盤產(chǎn)品質(zhì)量都是是塑料托盤里面質(zhì)量水平更好的。使用環(huán)境溫度可以在-40°~40°C條件下穩(wěn)定工作，使用壽命可以達(dá)到8~10年。
At present, the volume of blow molded hollow containers can reach thousands of liters. The large hollow forming machine developed and manufactured in China has reached 2000L, and the equipment is controlled by computer. Generally, PE can only be used as raw material in the production of blow molding tray. Therefore, the product quality of blow molding tray and injection molding plastic tray is the best in the plastic tray. The ambient temperature can work stably at - 40 ° ~ 40 ° C, and the service life can reach 8 ~ 10 years.
注塑成型的塑料托盤在使用性價比上和吹塑托盤是可以相媲美的，在上由于注塑工藝，上注塑塑料托盤比較占上風(fēng)，注塑塑料托盤產(chǎn)品品種齊全，尺寸多樣，可內(nèi)置鋼管，仍然占據(jù)塑料托盤行業(yè)主導(dǎo)地位，塑料托盤的使用，可以給物流等相關(guān)行業(yè)帶來很大的好處。一種發(fā)展迅速的塑料加工方法而成型的產(chǎn)品
Injection molded plastic pallets are comparable to blow molded pallets in terms of cost performance. Due to the injection molding process, the price of injection molded plastic pallets has the upper hand. Injection molded plastic pallets have a wide range of products, various sizes and can be built-in steel pipes, which still occupy the leading position in the plastic pallet industry. The use of plastic pallets, It can bring great benefits to logistics and other related industries. The utility model relates to a product formed by a rapidly developing plastic processing method
