Overmold Mold Maker | Custom & High-Precision Solutions

What is Overmolding, and What is its High Demand?

In overmolding, a rigid substrate or an already molded part is molded with a material that is generally a soft elastomer. This enables the manufacturers to make parts that are more grip, vibration-dampening, insulated, sealing, and comfortable parts without necessarily manual assembly.

A skilled overmold maker of molds will guarantee flawless adhesion between the two materials, eliminate interface shortcomings, and provide components that will feel elegant and strong.

It is used in:

• Electronics housings made of overmolded materials.
• Plastic components with soft grips.
• Overmolding of wire and connectors.
• Automotive overmold parts
• Sealed overmold components
• Medical device overmolding

Overmolding improves the performance of products, their feel, and their longevity, such as ergonomic toothbrush handles, strong automotive connectors, and many others.

Why is Selecting the Correct Overmold Maker of Molds Important?

The skill, technology, and engineering knowledge that your overmold mold maker has is directly related to the quality of your overmolded product. There is a fine balancing of temperature, pressure, bonding force, and shrinkage actions during overmolding, and therefore design of the moulds is highly technical.

An effective injection overmold manufacturer ensures:

• Top interface bonding (soft material + hard substrate)
• Zero delamination
• Proper compatibility of materials.
• Dimensional stability
• High tolerance control
• Extended mold life
• Shorter cycle times
• High-quality aesthetics of products.

This is the reason why collaborating with a professional overmold mold maker, such as SunOn, transforms the whole manufacturing process.

Learning the Overmolding Mold Design Process

An overmold of high quality demands a high level of structural engineering. There are dozens of important decisions during the design stage: the positioning of gates, balancing of runners, cooling scheme, and the choice of steel. The most significant design considerations utilized by the most successful custom overmold mold maker are as follows:

1. Overmolding Mold Flow Analysis.

Through superior software simulations, engineers visualize:

• Melt flow behavior
• Material viscosity
• Weld line locations
• Air trap zones
• Bonding interface dynamics

This gets away with the defects before the construction of the mold.

2. Gate Design Optimization

The correct position of the gates is necessary to make sure they achieve:

• Uniform material flow
• Reduced shear stress
• Balanced filling
• Increased sticking ability of materials.

The engineering team of SunOn relies on data-based approaches to optimize the geometry of gates on a project-by-project basis.

3. Runner System Engineering

A powerful runner construction minimizes pressure loss and enhances the strength of bonds.

• Cold runner
• Hot runner
• Hybrid runner systems

This action has a radical impact on the shaping of efficiency and cost.

4. Mold Steel Selection (H13, S136, P20)

The grade of steel defines the longevity of moulds and performance.

Typical choices include:

• H13 - Hard, best use with abrasive material.
• S136 - Excellent corrosion-resistant features.
• P20 - general-purpose molds

This technical peculiarity influences the process of shrinkage and heat dissipation.

5. Channel Optimization by Cooling

Properly designed cooling channels have minimized cycle time and facilitated dimensional stability.

SunOn integrates:

• Conformal cooling
• Baffle cooling
• The circuits are high-efficiency coolant.

Optimization of cycle time boosts production.

6. Ejection System Design

The ability to eject without scratching, deformation, or stress marks.

SunOn mixes:

• Pin ejectors
• Blade ejectors
• Sleeve ejectors
• Air ejector systems
