Overmolding & Insert Molding for Medical
FEATURES
- Overmolding & Insert Molding for Medical
Overmolding and insert molding are two common injection molding technologies that play an important role in manufacturing composite parts and integrating functions.
We have decades of experience molding onto metal and other substrates. Combining properties of different materials, such as strength and flexibility, can create more intricate designs for aesthetics, branding, or ergonomics.
Overmolding: Overmolding is an injection molding technology that covers one or more material layers on another base material. It usually involves two or more different materials, one of which is the base material and the other is the covering. The base material can be rigid plastic or metal, while the cover is usually a soft, elastic material such as silicone or thermoplastic elastomer (TPE). Overmolding can provide products with additional protection, anti-slip, shock absorption and other functions, while also increasing the appearance and feel of the product.
Insert Molding: Insert molding is a technology that embeds metal or other materials into plastic during the injection molding process. It involves placing one or more inserts (such as metal screws, electronic components, etc.) in an injection mold and then solidifying the plastic material around the inserts through injection molding. Insert molding allows the combination of plastic and metal to provide stronger connections and functionality. It is commonly used in the manufacture of products such as electronic equipment, automotive parts and medical devices.
Both molding technologies require special injection molds and equipment to achieve. In overmolding and insert molding, material selection and design are very important to ensure adhesion and compatibility between materials. In addition, factors such as temperature, pressure and injection molding parameters during the production process also need to be precisely controlled to ensure the quality and performance of the final product.
Overmolding and insert molding technologies can provide more design freedom and functional integration, while also reducing assembly processes and costs. They are widely used in many industries, providing new possibilities for product innovation and performance improvement.

- Medical Overmolding Capabilities
Overmolding is an injection molding technique that covers a base material with one or more layers of different materials to achieve additional functionality and appearance. Here are some common capabilities of overmolding:
Multi-material combination: Overmolding can combine different materials to achieve the desired performance and functionality. The base material can be rigid plastic or metal, while the cover can be a soft, elastic material such as silicone or thermoplastic elastomer (TPE). This multi-material combination provides better grip, anti-slip, shock absorption, sealing and more.
Improved appearance and feel: Through overmolding, the surface of the product can be covered with a layer of materials with different colors, textures or textures to improve the appearance and feel of the product. This can add personalization and a high-end feel to the product, improving the user experience.
Protection and protection: Cladding can provide additional protection and protective functions, such as waterproofing, dustproofing, corrosion resistance, etc. This is especially important for products that need to be used in harsh environments, extending the product’s service life and reliability.
Shock absorption and buffering: The soft coating can provide shock absorption and buffering effects, reducing the impact and vibration of the product during use. This is beneficial for products that need to protect sensitive parts or provide comfort.
Precise material positioning: Overmolding can achieve precise material positioning, ensuring that the overlay is in the correct position and angle. This is important for products that need to provide a functional or decorative effect in a specific area.
Overmolding injection molding machine equipment usually has the capability of two-color injection molding and multi-color injection molding, as well as the ability of liquid silicone rubber (LSR) injection molding. These capabilities make it possible to injection mold different colors or different materials in the same mold.
Two-color injection molding: Two-color injection molding refers to injecting two different colors of materials into the mold through the double injection system of the injection molding machine during the same injection molding cycle, thereby achieving a two-color effect of the product. This technique is often used to create products with different colors or logos, such as handles, buttons, grips, etc.
Multi-color injection molding: Multi-color injection molding refers to injecting multiple different colors of materials into the mold through the multi-injection system of the injection molding machine during the same injection molding cycle, thereby achieving the multi-color effect of the product. This technology is often used to manufacture products with complex patterns or gradient color effects, such as mobile phone cases, toys, etc.
LSR injection molding: LSR injection molding refers to the injection molding technology that uses liquid silicone rubber (Liquid Silicone Rubber) as the injection molding material. LSR has excellent high temperature resistance, weather resistance and softness, and is often used to manufacture products that require high elasticity and durability, such as seals, baby pacifiers, medical devices, etc. LSR injection molding usually requires specialized injection molding machines and molds to ensure precise injection and curing of the material.
The application of these injection molding technologies in overmolding can enable more diverse and complex product design and manufacturing. They require injection molding machines with appropriate injection systems, temperature and pressure controls, as well as precise material positioning and mold design. When using these technologies, it is necessary to select suitable injection molding machine equipment based on specific product requirements and production needs, and ensure that the operators have the appropriate skills and experience.
Overmolding injection molding machine is a kind of injection molding equipment specially used to achieve overmolding. It has some special capabilities and functions to meet the requirements of overmolding. Here are some common capabilities of overmolding injection molding machines:
Dual injection system: Overmolding injection molding machines are usually equipped with a dual injection system, which can inject two different materials at the same time. This makes it possible to injection mold the base material and cover layer in the same mould.
Temperature and pressure control: The overmolding injection molding machine has a precise temperature and pressure control system to ensure that the injection molding process of the base material and covering layer can be carried out at the appropriate temperature and pressure. This is crucial to ensure the adhesion and quality of the material.
Multi-cavity mold support: Overmolding injection molding machines can usually support multi-cavity molds, that is, multiple products can be injected simultaneously in the same injection cycle. This increases production efficiency and reduces production time and costs.
Precise material positioning: The overmolding injection molding machine has a precise material positioning system, which can ensure that the covering layer is injected at the correct position and angle. This is important for achieving complex cladding structures and assembly requirements.
Automation control: Overmolding injection molding machines are usually equipped with advanced automation control systems that can realize automated production processes. This includes automated mold opening and closing, material supply, injection molding process control, etc., improving production efficiency and consistency.
When selecting an overmolding injection molding machine, you need to select the appropriate equipment based on specific production needs and product requirements, and ensure that it has the required capabilities and functions. In addition, operators need to receive professional training and be familiar with the operation and maintenance of equipment to ensure the safety and stability of the production process.
