Insert Molding

Custom Insert Injection Molding Service

Insert injection molding is a injection molding process that with start placing metal into the mold, then the mold cavities filled with molten plastic. Once the plastic has cooled, the inserted parts are firmly bound to, and integrated into, the plastic parts. Inserts can be steel, screw brass, magnets, Aluminum, or just about any substance that can withstand injection molding process. Insert molding is a lower-cost alternative to other manufacturing methods

Custom Insert Molding Manufacturing Specialist

Vertical injection machine are beneficial for insert molding. With vertical molding, molds open and close on the y-axis, allowing gravity to do the work of holding inserts in the mold and eliminating the need for a specially made mold.

The plastic molding process calls for very high accuracy to ensure that the resulting plastic parts are properly formed. Even a slight misalignment can completely ruin the outcome, hence the need for very tight quality control procedures. 

We having replaced the operator handloading and removing of an insert with the loading and removing of those inserts by precision robotics. The introduction of and expertise in the use of this automation minimizes the variables that affect final part quality by ensuring a consistent, reliable, and repeatable process.

Quality Insert Molding Tooling Making

The right mold design and construction are critically important in insert molding to maintain part tolerances and tooling reliability. Ultra precise tooling making forms the basis for the quality of the insert molding in series production. 

The mold of insert molding necessitates extremely tight tolerances to ensure the proper formation of the plastic parts being created. The slightest misalignment of even a fraction of a millimeter can lead to the ultimate failure of the molding process.

Our mold designer evaluate both machinability, design for manufacturing and durability in their designsBesides Moldflow analysis, we use our years of experience in constructing molds. 

Insert Molding Manufacturing Core Critical Point

In the insert molding process, the mold is specially designed to hold the inserts in place, allowing plastic resins to flow and harden around the inserts. A completed part or inserted component is then ejected from the machine with the inserts installed. This process eliminates the need for post-production assembly and ensures a tight bond between the plastic part and its inserts. Below is some key points that we summarized about insert molding products manufacturing according to our experience:
  Mold Making Feasibliity
■  Inserts Easy to Fit and Fixed
■  Inserts Must be Tight Tolerance
■  Cavities Quantity
■  Design for Manufacturability
■  Mold Design
■  Gate type ,Location, Quantity
■  Mold Machining Tight Tolerance
■  Vertical Molding If Available
■  Automation Production
■  The Insert Must be Inserted Precisely
