Successful case of repairing the broken foot of the sealing ring on the lid of an ASD soy milk machine

In May 2014, Zhejiang Aishida Household Appliances Co., Ltd. developed a new type of soy milk machine. During trial production, it was found that the machine head cover seal ring was prone to breaking at the foot during installation, with a defect rate of 80%. The previous supplier had repeatedly modified the mould but never provided Aishida with a qualified sample. For this reason, the project was shelved and subsequent production could not proceed smoothly. In June 2015, the company's technicians brought the defective seal rings to our company. After research by our technical team, it was discovered that the cause of the seal ring defects was due to unreasonable mould and production process design, which led to breakage at the foot of the seal ring. Through joint efforts in mould and production at our company, we eventually produced qualified samples using the liquid injection moulding process, resolving the issue of easy breakage of Aishida seal rings. While solving the customer's problem, this also tested our company's efforts and capabilities in mould technology.
