Plastic injection molding

Plastics technology

As one of the most important materials in industry, plastic is extremely versatile, durable, and cost-effective. Modern and proven processes such as thermoplastic injection molding—for example, two-component injection molding—enable you to cost-effectively and sustainably manufacture directly bonded molded parts in every conceivable variation.

As specialists in injection molding, we at Plastium have been rising to the challenge for many years of supporting our customers with injection-molded parts from the initial idea through to the market-ready end product. Using state-of-the-art injection molding machines, we also manufacture first-class components and assemblies for you that meet your technical requirements as well as the increasing cost pressures of the market.

Why use injection molding for plastic processing?

Why use injection molding for plastic processing?

Using injection molding for plastics processing helps you produce even the most complex designs at attractive costs. With precise manufacturing of suitable molds and tools in advance, the molten plastic can be shaped into virtually any conceivable form to allow it to cure evenly. Afterward, direct assembly and combination with other plastic parts or components made of other materials is possible.

Two-component injection molding in a single operation

One of Plastium GmbH’s core competencies is the production of directly bonded plastic molded parts using two-component injection molding, or 2K injection molding for short. For the two components, you can choose from the following materials:

  • Thermoplastic + TPE – for ergonomic, non-slip surfaces
  • Thermoplastic + Thermoplastic – for particularly durable components

Two-component injection molding in a single operation

How exactly does two-component injection molding work?

In the two-component injection molding process, both materials are processed directly into a single finished part in a single operation without the use of a bonding agent. Chemical and/or physical methods such as clamping, overmolding, or back-molding can be used to bond the two materials.

Once your molded parts have cooled after the plastic injection molding process, you enjoy the major advantage of not having to invest any additional effort in post-processing or assembling your parts. Quality inspection costs can also be reduced with injection molding, while the right combination of materials for your injection-molded parts allows you to tailor the properties and functions of your components to virtually any application.

An Overview of the Advantages of the 2K Injection Molding Process

Overview of the benefits of the 2k injection molding process

2K injection molding is the modern production method for injection-molded parts, offering you significant advantages over traditional injection molding processes:

  • Cost efficiency: You significantly reduce the number of assembly and machining steps.
  • Functionality: Multiple functional properties can be integrated into individual components.
  • Surface design: Color accents, smooth transitions, and more are easily achievable.
  • Sustainability: You save on material and benefit from short cycle times

A single production run to the finished part

Reducing time, effort, and costs is a top priority in every industrial project. This is where plastic injection molding—using processes such as two-component injection molding—is ideal, as it allows you to produce a finished part with the highest precision in just a single production run. After a one-time mold or tool design, you can use your injection mold to continuously produce precise, high-quality parts in series and make your operational processes more modern and efficient.

An overview of various processes

Our extensive machine park enables us to manufacture plastic parts using a wide range of established, quality-focused processes. We combine traditional methods for producing injection-molded parts with innovative techniques. Here is a brief overview of the key processes offered by Plastium GmbH:

1. Two-component injection molding

Our production process focuses on joining two plastics with different material properties into a single injection-molded part. The result is a reliable and strong bond that is precisely tailored to the specific application in terms of strength, density, size, and other parameters.

2. Assembly injection molding

In assembly injection molding, the second step following injection molding involves the assembly of the part with additional plastic or metal components. This allows the finished part to be produced in a single operation; we design custom machines and systems for you that automate this step.

3. Insert molding

Do your plastic parts need to have threads for screw-on assembly in later stages? Using insert molding, we manufacture the necessary components by overmolding your metal or plastic threads.

4. Screw-on mounting

The screw-in technique is also used to connect your plastic part to a threaded component. Unlike insert molding, the thread is inserted into a cavity in the pre-manufactured plastic part.

FAQ

is the 2k injection molding process suitable for my needs?
Injection molding is ideal if you want to produce complex shapes for your components and expect versatile applications using different plastics with their respective properties. In addition to the shape, wall thickness, design, density, and many other parameters can be easily controlled and adjusted using two-component injection molding.
Why is injection molding so cost-effective?
Plastic injection molding requires fewer molds than traditional methods, which means lower investment costs for your company. Production is significantly more efficient with fewer steps, and the ability to automate ensures consistent quality for you and your customers. In addition, you reduce the total cost of ownership (TCO) through integrated processes.
In which industries is 2k spray painting primarily used?
Typical applications include handles, control buttons, and soft-touch components in the automotive industry, as well as safe and sterile plastic parts in medical technology. Ergonomic control elements for various household appliances can be manufactured using plastic injection molding, while switches, housings, and insulation components in the electrical engineering sector can be produced in this way.
Is plastic granulate or powder used in injection molding?
In plastic injection molding, plastic pellets are typically used, which are melted in the injection unit. The molten pellets are then injected into the mold cavity, where the material displaces the air and precisely fills even the smallest details of the mold. Powdered materials are not commonly used in two-component injection molding.
Is plastic injection molding an environmentally friendly process?
When it comes to sustainability, plastic injection molding offers significant material savings in some cases, as well as reduced part weight, which leads to lower transportation costs. Faster production helps you save energy, while the highly precise manufacturing of molded parts allows you to significantly reduce waste.
Would it make sense to include installation work?
Whether subsequent assembly should be part of the production process depends on the finished component or product. Ideally, the entire part can be manufactured in one or more components using a single mold via plastic injection molding. When joining plastic and metal, an additional process is usually required, such as assembly injection molding.
