The price of customized plastic molds is influenced by various factors, such as the complexity of the mold, materials used, production quantity, manufacturing process, etc. Generally speaking, the cost of molds includes design fees, material fees, processing fees, assembly fees, and acceptance testing fees.

For simple molds, the price may be around a few hundred to one thousand RMB. For more complex molds, the price may be higher, reaching several thousand or even tens of thousands of RMB. However, the specific price still needs to be evaluated based on the actual situation.

It should be noted that the price of molds may also be influenced by factors such as the manufacturer's scale and experience, market competition, etc. Therefore, if you need specific prices, consult multiple mold manufacturers to understand their quotes and services in order to make informed decisions.
