Product Process
Insert injection molding involves inserting a metal, ceramic, or
other preformed component into the mold cavity during the injection
molding process and fusing it with the plastic to form a single
piece. This process enables products to maintain lightweight while
also achieving increased strength, conductivity, or specialized
functions. It is widely used in industries such as electronics,
electrical appliances, automotive, and medical devices.
Process Flow
- Mold Design: Determine the insert's position and structure to
ensure a secure bond
- CAD/CAE Analysis: Optimize plastic flow and insert positioning
stability
- High-Precision CNC Machining: Complete the mold cavity and insert
mounting groove
- Mold Assembly: Add positioning devices and a cooling system
- Mold Trial Verification: Test the insert-plastic bond strength and
product performance

FAQ
Q1: What is the difference between an insert mold and a
conventional injection mold?
A1: An insert mold allows metal or other components to be embedded
in plastic in a single step, enhancing the functionality of the
product.
Q2: Will the insert loosen?
A2: Proper cavity design and melt encapsulation can ensure a secure
bond.
Q3: Is insert molding suitable for automation?
A3: Yes, an automated insert robot system can be designed.
Q4: Are there any restrictions on the insert material?
A4: Common metals, ceramics, and high-temperature-resistant
materials can be used.
Q5: Does this increase mold processing difficulty?
A5: Yes, but this can be effectively addressed through precision
CNC and CAE analysis.
Q6: What is the typical mold lifespan?
A6: Under normal use, it can achieve up to one million mold cycles.
