The main production processes of vacuum molded products include molding, pulling, punching, folding, punching, packaging, etc. The following will introduce them separately.
Mold lifting
After the customer confirms the sample, the gypsum mold used for sampling is used as the mother mold, and after electroplating copper, the production mold is made according to a certain quantity and position, which is called the lifting mold. There are three types of conventional molds: gypsum molds, copper molds, and aluminum molds.
Gypsum molds are mainly used for sampling and cannot be used for mass production. Their production time is generally 24 hours. The copper mold is a gypsum mold electroplated with a layer of copper, which enhances strength and wear resistance, and is not expensive. It is the most commonly used mold in production, with a general production cycle of 100 hours, at least 3 days, and a service life of about 100000 pieces. When the quantity reaches one million or more, aluminum molds can be made.
Aluminum molds are made of pure aluminum, which is costly and requires machining. Generally, the mold making time is 3 days. Aluminum molds have good production quality, fast heat dissipation, high product accuracy, and long service life. If customers require precise products and copper molds cannot meet the accuracy requirements, even if the quantity is small, aluminum molds must be made.
