   1. Amorphous materials, with abs plastic Moulding fluidity and hygroscopicity, need to be fully dehydrated. Plastic parts with glossy surface should be preheated and dehydrated at grade 80-90 for 3 hours for many years
   
   2. The heat of the material and the heat of the mold should be more, but the heat of the material is too high and easy to decompose (decomposition temperature> 270 degrees). For plastic parts with high precision requirements, the mold temperature needs to be between 50-60 degrees, and there must be a good gloss. For thermoplastic parts, fungus temperature should be 60-80 pass
   
   3. If you want to remedy the water mark, you need to improve the fluidity of the fabric, accept high material temperature, greater mildew temperature, or change the water level and other methods
   
   4. If molding heat-resistant or flame-retardant parts, after 3-1 weeks of manufacture, plastic decomposed products will stay on the top and become moldy, making the top of the fungus sparkle. In fact, it is necessary to clean up the mold in time, and the mold above must increase the exhaust situation
   
   5. The speed of cold water is fast, the mycelium pouring procedure should conform to the basic principles of dense and fast, and the cold cloth hole should be set up, and the gate should be large, including: direct gate, disc entrance or lover entrance, etc., but internal pressure should be prevented. A variable entry can be used if necessary. The mould should be heated and durable stainless steel should be used
   
   6. The temperature of the contents has an excellent influence on the quality of plastic-like material parts. If the fabric temperature is too low, there will be a general shortage of material, dry surface area, cluttered sterling silver threads, and of course, if the information temperature is too high, it tends to spill over the edges, dark streaks of metal threads can appear, and plastic material components will eventually discolor and play Bubble
