1、 Pattern tire appears on the surface of the barrel
1. Foreign objects in the cavity. Park and clean with a dust gun
2. If the temperature of the material cylinder or machine head is too high, adjust it appropriately to reduce the temperature of the material cylinder or machine head.
3. Insufficient inflation pressure or short holding time, adjust and increase inflation pressure or holding time.
4. Mold temperature is too high, check for water circuit issues.
5. Scratches on the mold head. Polish smooth with a grinding wheel
2、 Stripe marks appear on the surface of the barrel
1. If the temperature of the material cylinder or machine head is too low, adjust the temperature of the material cylinder or machine head appropriately.
2. Insufficient inflation pressure or short holding time, adjust and increase inflation pressure or holding time.
3. The mold temperature is too low, increase the mold temperature appropriately.
4. The flowability of the raw materials is too poor. Adjust the process and replace the formula.
5. If the mouth mold is scratched or there are impurities remaining at the mold head, the mouth mold should be polished or copper sheets should be used to clean the impurities at the mold head.
3、 There are pitting marks on the surface of the barrel
1. The material temperature is too low, raise the temperature of the material cylinder or machine head.
2. During process adjustment, the sol stays in the barrel for too long.
3. Poor plasticization, increase or decrease the temperature of the material barrel.
4. Poor fluidity of raw materials, adjust the process and replace the formula.
5. Insufficient blowing gas pressure, adjust blowing gas pressure or increase mold temperature.
