Collapsible core design for undercuts injection molding

• Collapsible core injection molding

Overmolding & insert molding manufacturer Upmold is injection molding experts and serve many different industries including medical device, aerospace/defense, consumer products, electronics, and automotion. Their expertise is in medical injection molding but provides a wide range of products to many different sectors and ship parts all around the world.

One service that is often overlooked is their specialization in overmolding. Overmolding is often confused with insert molding since it is performed on the same injection molding machines. Overmolding vs insert molding is actually more simple than what most companies make them out to be. Overmolding is a subset of insert molding. All overmolding is insert molding, but it does not go both ways.

There are many different preferences to what shops call overmolding and insert molding. Insert molding is often when a pre-produced part is inserted into a mold and receives a mold around it.

Overmolding is a similar process but it is typically when a part needs a second operation over the initial insert molding. It is still an insert molded product, but referred to as overmolding. Overmolding vs. insert molding is also commonly referred to as “injection molding with a second operation”, or “insert molding with an over-molded sequence.”

The advantage to using a vertical injection molding machine for either insert molding or overmolding are the following:

• Don’t have to fight gravity to keep the part in.
• Quicker yields (especially when used with bookmolds and rotary tables).
• More flexibility for mold designs

• Reduces the chance of damage to the part due to friction during release
• Reduces wear and tear and chances of damage to the mold
• Ensures a uniform, smooth, unscratched finish when required
• Ensures the integrity and uniformity of other surface finishes and textures
• Reduces overall cooling time by lessening or eliminating the need for unconventional ejection setups
• Most, if not all, of these benefits offer either direct or indirect overall production cost reductions
