A few days ago, Taili Plastic Machinery visited customers in Jinhua and heard some complains from Mr. Li, who is 45 years old and has been engaged in injection molding industry for more than 20 years. But as for his most familiar product, he has to admit that he is not as good as Mr. Chen, who only joined the industry last year, in terms of market and quality. What's the secret? Today, Taili Plastic Machinery will share with you!

Mr. Wu of Jiangxi is a manufacturer who mainly produces storage boxes. Strangely, after each product is produced, he will press it with a book for 30 seconds, and then release it after it has cooled down completely. Does he aim to make the product read more so as to sell at a higher price?
