I am looking for reputable custom silicone mold manufacturers who can provide high-quality molds for a new product line. The molds must be durable and able to recreate intricate designs. I need manufacturers who can produce a minimum order quantity of 100 pieces and can deliver within 4 weeks. Additionally, they should be able to accommodate minor design modifications, as my product will undergo iterative improvements based on initial feedback. If you are a manufacturer with experience in this area, please get in touch.
