Our plastic injection moulding machines are thermoset-system which has special barrel-screw. At the beginning of my work experience, I also talked with other handle manufacturers which have consumption over 20toones/month. They all said that they import the raw material from China, Taiwan, and India. They cannot use the local manufacturer material. They also talked to change their formula but them and I cannot give any result from them. I believe that they do not know scientifically anything about phenolic-moulding compound. Therefore the Chinese injection moulding companies that compete with the other countries import raw material. In China, the total custom rates are %18+%7. When you consume 30tonnes/month or higher, those costs really affects us.
