Insert Molding is a process of inserting bolt, nut, electrode piece and other metal components into plastic parts. Place the components in mould in advance, the insert component will be tightly and stably assembled with plastic product after injection. Now, it’s widely used in electric, appliance, pipe fitting, hand tool and more industries.

In addition, if using a plastic part as insert component, insert molding process could be used for manufacturing two color product. Without multi shot injection machine, we could also produce colorful and beautiful products.

Insert Molding Has The Advantages As Below:

High productivity, lower the labor cost

Components are closely assembled, more stable and durable

Environment friendly, no pollution from secondary fixture

CASE STUDY

INSERT MOLDING OF DOUBLE COLOR BASIN

CHALLENGES

The double color basin produced by inserting plastic decoration component into the basin mould and through insert molding process, the product will have appearance in double colors. The plastic insert has more uncertainty of shrinkage than metal insert. Therefore, controlling the shrinkage allowance between plastic insert mould and principal mould is a key element in the insert molding process.

ENGINEERING & TECHNOLOGY

Having rich experience, Jeward design team could calculate accurately the shrinkage allowance of mould according to the target materiel. We do repeated test in mould testing period and record the best parameters. So that customers could set up the their injection machine quickly after receiving our mould.

Insert Molding

SOLUTION & RESULTS

Due to the reasonable use of shrinkage and high processing accuracy, our double colors basin has flat joint without shortage and flashing. Our mould could go into production quickly in customer’s factory by referring to our mould testing parameter, which saves lots of testing trouble.
