For every project, we will do the mold analysis and communication with customers. Problems can be solved before the mold starts and bulk production. For any design update from customers, we are trying best to do the least expensive way to revise the mold. For each bulk goods shipped, we get the material certificate from our raw material supplier to ensure the quality. For any problem issues found in customer's side, whether caused on our side, by the shipping, or on customer's side, we will do our part to solve the problem and maintain the long-term cooperation.
