heavy duty plastic pallet

Why we made of black masterbatch product surface appear pitting? If is concave pits, black neps material volatilize, prove that adding a lot of black hair grain of white oil.

Why we made of black masterbatch product surface appear pitting? If is concave pits, black neps material volatilize, prove that adding a lot of black hair grain of white oil. Plastic tray in black masterbatch containing calcium euro plastic pallet carbonate is too much, may be MOIN lumps of mechanical equipment, and can't leave. At this time, we must change the concentration of low black masterbatch, or will withdraw more slippery, masterbatch, to produce more machinery and equipment, can make the perfect plastic tray.
If our plastic pallet in the wild by ultraviolet sunlight and do not use, we can use calcium carbonate content is 10% of the black base, the base price is low, on average, color is not affected, the surface of the light is good, to the heavy duty plastic pallet requirements of the product's strength is small, if the inside of the calcium carbonate is too low, plastic tray surface becomes rough, the intensity of landing color also won't shine.
What is the cause of the plastic tray have off color? If the light plastic pallet is not good, may be too much residual gas injection in the process of the mould, check and correct the mold exhaust system. We accept the injection mould of plastic tray, if long time not to wipe, can produce oily be soiled, dirt, may release agent is overmuch, can make the plastic pallet surface dark heavy, black. Therefore usually pay attention to the injection molding machine maintenance, wipe off the dirty mimeograph, with more release agent. Plastic tray is stackable plastic pallets another case of bad light demoulding wrong Angle, Angle is a little small, lead to a difficult demoulding, lead to off color, need to adjust the Angle. If the mould itself is bad, uneven, such as scratches. On the above will lead to bad color.
Fracture factors: plastic tray plastic tray manufacturing mold temperature and injection temperature improper configuration; Insert the direction misallocation or not preheating; Plastic pallet manufacturing process of random loading and unloading; Plastic tray is the biggest reason for product structure is not fair, directional injection molding process of produce internal stress, especially along the direction of material movement is easier to crack; Because of the wrong material brand or no return too much destroy plastic pallet box original molecular structure. Disposal methods: mediation molding technique and post processing skills; Choose suitable for thick wall material, using new materials; In the process of work handled with care; Optimization scheme, reasonably adjust the mold temperature and injection temperature preheating insert.
