Plastic Injection Molding

Plastic injection molding procedure utilizes plastic materials to make a custom mold after the raw substance is heated, melted, and cooled down. The customized plastic mold is used to manufacture bulk quantities of plastic parts. 

Clean Room Injection Molding

With Class 8 clean room, Seasky can customize plastic injection molding for many industries with high molding environments. Plastic aerospace components and medical device components can be customized here.

Insert Molding

Insert molding integrates top-notch machines to construct creative, intricate parts via the procedure of molding or shaping plastic components around other inserts. Insert molding is ideal for manufacturing high-precision customized plastic molding parts for various industries. 


The overmolding procedure integrates two or more plastic materials in one final item. In this procedure, the base material is molded initially, and the extra plastic materials are molded around the first material to produce custom plastic injection molders


Two Shot Molding 

Two-shot molding is also known as double-shot, dual-shot, and 2k injection molding. In this custom injection molding procedure, two distinct plastic materials are combined in one machining cycle. 

Benefits Of Custom Plastic Injection Molding

Custom plastic molding is relatively beneficial, which is why companies rely on Seaskymedical injection molding processes for manufacturing bulk quantities of custom plastic injection molds

Plastic Parts Strength & Stability

The customized injection molding process ensures that the final items are robust, resist temperature, withstand harsh conditions, and show impact resistance as only premium quality medical grade materials are used. 

High Efficiency & Enhanced Performance 

The custom injection mold technology is highly efficient, and our skilled designers only use advanced tools and reduce unnecessary expenses. We have the latest custom plastic injection molder machines that meet high-performance criteria. 

Complex Design Capabilities 

Custom plastic injection molding machines have the capability to develop complex plastic parts without even missing minute details. With this technology, it is easy to make custom plastic injection mold parts in several shapes, designs and sizes with customized structure details. 

Detailed Features 

It is possible to add intricate details to the custom plastic injection moldings and also improve the overall functionality and aesthetics to highlight your brand. The final products can have customized brand text, various surfaces, multiple color options, etc. 

Material Variety 

For manufacturing custom plastic injection molds, there are various medical-grade material choices like Silicone, Acrylonitrile Butadiene Styrene (ABS), Polypropylene, PEEK, High Impact Polystyrene (HIPS), Polyethylene, Nylon, etc. 

Environmentally Friendliness 

Customized plastic molding parts are likely to remain in good working condition for a long time because of their quality and resilience. In addition, there will be little to no wastage custom injection molding process. 

Custom Plastic Injection Molding Process

SeaskyMedical is a high-class Chinese plastic molding company that offers a one-stop injection mold service. In the custom injection molding process cycle, there are four different stages, which are clamping, injection, cooling, and ejection. Firstly, a plastic substance is heated till it turns into a viscous melt, which is then pushed into the closed mold design machine. When the plastic substance in the mold is cooled down, it turns into a solid-shaped product that is taken out from the opened mold machine.

Selecting Materials For
Custom Plastic Molding

At SeaskyMedical, we offer various material selection options to ensure that the manufactured custom plastic injection molders meet the client’s specific requirements. We use only medical-grade premium raw materials. As there are plenty of material choices, we consider some vital factors in choosing the best material that is ideal for the application. 


Based on how the final injection molding custom product will be used, the environment it will be used, and the needed abrasion resistance, the hardness of the raw material should be considered. The hardness of plastics is gauged and depicted by number values on various scales like shore 00, shore D, or shore A. 

Flexibility & Impact Resistance ​

The stiffness or flexibility factor depicts the resistance strength of the substance against stress. It is also vital to inspect the impact resistance to check if the custom plastic injection mold material will handle harsh conditions and varying temperatures. 

Part Weight ​

When it comes to plastic materials, their density or mass differs greatly, which is why the part weight can also differ significantly for the specified part volume in cubic cm. If the wrong substance is selected, excess prices will arise during the whole customized plastic injection molding life cycle. 

Material Cost ​

To create a customized plastic mold, various types of materials are accessible in the market in different price ranges. Considering the material cost is vital to choose the right material as per the application.
