What is Injection Molding

Injection molding is a manufacturing process widely utilized for producing parts by injecting molten material into a mold. This material could be plastic, metal, ceramic, or glass. The mold is custom-made and usually constructed from metals like steel or aluminum. Once the molten material is injected into the mold, it cools down and solidifies into the shape of the desired part.

As a matter of fact, according to PRNewswire, the global injection molding market size is estimated to increase by USD 30.65 billion from 2022 to 2027. The market’s growth momentum will progress at a CAGR of 4.14%. The rising adoption of high-efficient injection molding machines in the packaging industry is driving market growth and continuously rising demand for sustainable solutions.

Applications of Injection Molding

Aerospace Plastic Injection Molding

Aerospace companies often turn to plastic injection molding for the production of lightweight, durable parts. The aerospace industry requires components with tight tolerances and high performance in extreme conditions. Injection molding allows for the production of complex geometries and material combinations to meet these stringent requirements.

Industrial Injection Molding

Industrial applications of injection molding are vast and varied. From construction equipment to machinery components, the process offers the precision, efficiency, and material versatility needed in the industrial sector. For example, high-performance plastics and metals can be molded into durable parts that withstand harsh environments.

Automotive Injection Molding

Automotive manufacturers heavily rely on injection molding for producing a plethora of components, from dashboard elements to engine parts. The automotive sector requires high-quality, durable, and lightweight materials to improve performance and fuel efficiency. Suproto’s partners in this industry have seen that injection molding is an ideal choice due to its precision, cost-effectiveness, and material options.

Sizes of Injection Molding

Large part injection molding is essential for manufacturing big components, such as automotive bumpers, large containers, and panels. We at Suproto understand this process uses larger molds and higher press tonnage to produce parts that are too big for standard injection molding machines.


The mass production of parts, regardless of their size refers to large scale injection molding. This is often employed when there is a need for a large quantity of parts to be produced efficiently and cost-effectively. This method is widely used in industries such as automotive, consumer goods, and packaging.

High Volume Plastic Injection Molding

High volume plastic injection molding is an excellent choice for producing substantial quantities of plastic parts with unswerving quality. In this process, molten material is injected into a mold, which then cools and solidifies into the desired shape. This method is particularly advantageous in industries like automotive and consumer electronics, where the demand for large quantities of consistent parts is paramount.

Low Volume Injection Molding Companies

In contrast, low volume injection molding companies are known for their focus on quality and maintaining high standards without compromising on speed, in a competitive market. Low volume injection molding services in companies are an efficient and cost-effective method for producing smaller quantities of high-quality plastic parts. This approach is mainly employed for prototyping, market testing, and small-scale production.

Small Batch Injection Molding

Moving forward, small batch injection molding takes low volume molding a step further by focusing on extremely limited production runs. This is the go-to option when only a handful of parts are required, often for custom applications or niche products. Small batch injection molding is especially beneficial for startups and businesses that need to test a concept without investing heavily in mass production.

Small Quantity Injection Molding

Small quantity injection molding is akin to small batch molding but typically involves even lesser quantities. It’s an optimal choice for scenarios where only a few prototypes or replacement parts are necessary. The smaller quantities allow for a more hands-on approach, ensuring that each part meets precise specifications.

Injection Molding Contract Manufacturing

Injection molding contract manufacturing involves outsourcing the production of injection-molded parts to a third party. At Suproto, we believe that this allows businesses to leverage the expertise and capabilities of specialized manufacturers. Check it out with our team!

Types of Injection Molding

Precision Injection Molding

Precision injection molding is an essential technique that involves producing components with extremely tight tolerances. In industries such as aerospace and medical devices, the margin for error is minimal, so precision is critical to ensure the reliability and safety of the products. Moreover, molds for precision injection molding are often made from steel or aluminum and are precision-machined to get the desired parts with high accuracy.

Rapid Injection Molding

Transitioning to another type, rapid injection molding is a process that combines speed and efficiency to produce low volumes of parts. This method is ideal for prototyping or initial market testing, as it enables manufacturers to quickly produce parts and make necessary adjustments before mass production. Utilizing rapid injection molding not only accelerates time-to-market but also significantly reduces development costs.

Clean Room Injection Molding

Suproto’s clean room injection molding is employed for the production of parts in an environment that is free from contaminants. Given that certain industries such as medical, pharmaceutical, and electronics require stringent cleanliness standards, clean room injection molding ensures that components are free from any contaminants that could affect their performance or safety.

Complex Plastic Injection Molding

Venturing further, complex plastic injection molding is a technique employed to create highly intricate and detailed plastic components. This process requires advanced mold designs and processing technologies to successfully produce complex parts with precision. It is widely utilized in various industries where complicated shapes and designs are required, such as automotive, consumer electronics, and aerospace.

Core Puller Injection Moulding

Core puller injection molding is a specialized process where the mold contains movable sections known as core pulls. These core pulls allow for more complex shapes and features to be molded, which would not be possible with standard molds. This technique is crucial for creating parts with undercuts or those that require hollow sections, and is employed in various industries ranging from automotive to consumer goods.

Low Cost Injection Molding

For low-cost injection molding, it plays a vital role for businesses aiming to reduce manufacturing expenses while maintaining quality. This process typically involves optimizing the production process, utilizing cost-effective materials, and implementing efficient molding techniques. Such an approach is fundamental for small businesses or those with tight budgets, as it allows for the production of high-quality parts at a reduced cost.

5 Considerations When Choosing Injection Molding Services

#1 Material Selection

Material selection is imperative for the performance and durability of the injection molded parts. It is essential to take into account the environmental conditions and the physical stresses the parts will be exposed to. For example, Polypropylene (PP) is a popular choice for injection molding due to its high strength-to-weight ratio, high rigidity, and low moisture absorption.
