The backbone of Pet Bottle Preform molded is carefully accompanying to the abstracts used, so affliction accept to be taken in the best of cast materials. In general, the cast actual should accept the afterward characteristics:

(1) Top abrasion resistance

In adjustment to access the acerbity and automated backdrop of artificial parts, bottle fibers and asleep fillers are broadly acclimated in artificial formulations. After the accession of these additives, they access the cast atrium at top acceleration forth with the aqueous material. The abrasion central the cast atrium is actual large. If the cast actual is not abrasion resistant, it is simple to accomplish a atrium underwear. Therefore, the actual acclimated to accomplish such a cast should accept bigger abrasion resistance.

(2) Top bane resistance

Many artificial additives, such as blaze retardants, and even the actinic activity of the cook itself can bite the cast cavity. When artificial abstracts are alloyed with annoying fillers and reinforcing materials, it is added acceptable to could cause accident to the mold. In this case, it is bigger to use corrosion-resistant animate or to accomplish electroplating, chrome plating or nickel plating on the mold.

(3) acceptable thermal conductivity

In bang molding, acceptable cast temperature ascendancy has a abundant access on the superior of artificial parts, abnormally in the processing of semi-crystalline thermoplastics. Copper alloys about accept abundant bigger thermal application than admixture steels, but their modulus of elasticity, acerbity and backbone are lower. Insufficient thermal application of animate can be compensated by the cooling system.

(4) acceptable dimensional stability

In the abstraction operation, the temperature of the atrium is college than 300 degrees Celsius, and the temperature aberration is so ample that the microstructure of the atrium can be calmly changed. Therefore, the admeasurement of the cast changes and the admeasurement of the artificial allotment is unstable. Therefore, it is accessible to baddest a appropriately choleric apparatus steel, that is, heat-treated steel. In adjustment to advance acerbity and abrasion resistance, the cast accept to be calefaction treated. However, this calefaction analysis should abbreviate the admeasurement of the cast and can be acclimated to cut pre-hardened animate that is machined after calefaction treatment.

(5) Acceptable cutting performance

The close bank of the atrium is actual top and the acerbity is actual baby to accommodated the requirements of acceptable appearance on the apparent of artificial parts. In this case, the atrium is usually polished. The bigger the surface, the bigger the cutting of the cast material.

Jilian cast is actual able in the actual alternative of the mold, and our pet blowing machine is aswell actual complete, and the account activity is aswell actual long.
