Injection molding solutions for contract manufacturers

Flexibility in the production of plastic parts

The variety of plastic components is extensive. Daily production poses challenges like frequent tool and material changes and the efficient startup of new tools without compromising time or performance. The cost pressure is just as high, coupled with fast delivery times. Our injection molding solutions for contract manufacturers enable flexible and efficient production of your plastic parts.

Benefit from our injection molding expertise as a contract manufacturer

Focus on your solution Thanks to our broad portfolio of injection molding machines and automation solutions, you will receive a system tailored to your needs.

Rapid availability With our fast track series and our stock machine program, we guarantee fast availability of your system within a few weeks.

Flexibility Our injection molding machines and their range of options give you a high degree of flexibility in the production of your plastic parts.

Your advantages in injection molding contract manufacturing with us as your partner
Quick mold changes thanks to tie-bar-less machines

Frequent tool changes are a challenge for contract manufacturers in injection molding. This is because they reduce the availability of injection molding machine time. Thanks to the tie-bar-less design of our victory and e-victory machine series, you can change your molds in under 10 minutes. The absence of tie-bars makes it easier for the operator to access the mold area during the set-up process.

Efficient set-up with the menu-guided tool change

The set-up assistant is a checklist that guides the machine operator through the individual steps required for the tool change. The set-up assistant program automates program steps whenever possible with manual tasks noted in the control system. This means that even less experienced employees can set up safely and without errors. The set-up assistant increases efficiency for experienced set-up teams.

Easy color and material change thanks to self-cleaning package
Picture shows front part of a plasticizing unit from ENGEL

When colorant or material is changed during the production of plastic parts, streaks form on the component. Streaks are the result of mixing old and new material. It is therefore not possible to produce good parts for a certain period of time. We have developed the self-cleaning package to keep this period as short as possible and to quickly restore the production of high-quality parts. The modified screw tip enables you to change colorants and materials quickly. Your benefits: increased productivity and material savings.

Stable production with iQ weight control

The intelligent iQ weight control assistance system regulates every injection process during production. It corrects the injection volume and calculates the switchover point of the injection molding process in the same shot. Fluctuations are compensated for in each shot. This reduces the variation in the weight of the molded part by up to 85%. Your benefits in injection molding contract manufacturing: more stable processes, increased part quality, faster start-up after tool changes and exact repeat accuracy, even with recycled material applications.

Reduced footprint thanks to HLi automation solution

To counteract the lack of space in your production hall, we have developed our compact HLi solution (High Level Integration). The conveyor belt of the system is integrated into the safety guarding of the injection molding machine. Therefore, the robot is protected. Access to the mold area via the non-operator side is still possible. The HLi solution also offers the option of installing additional peripheral devices under the conveyor belt. The result: a compact overall system for injection molding contract manufacturing without taking up unnecessary floor space.

Full integration of automation

From simple parts handling to complex production cells, we can supply a system tailored to your requirements. Our injection molding systems are UL-certified. The automation is fully integrated into the CC300 machine control system, allowing programming and parameterization directly within the system.

Reduce energy costs with ENGEL solutions

We do not only consider the injection molding machine, but the entire system. By optimizing the drive concept, temperature control, intelligent device communication and smart process control, we achieve maximum efficiency for your system. This enables you to reduce the power consumption and CO2 emissions of your injection molding cell by up to 67%, depending on the application. You can save a further 20% energy with our energy efficiency packages.

Supporting ENGEL solutions for contract manufacturers in injection molding
  • Tool change in under 10 minutes

    From the last to the first good part in 10 minutes - fast and efficient tool change on a tie-bar-less victory 80 tech.

Frequently asked questions from contract manufacturers in injection molding

One way to set up tools more quickly is to use tie-bar-less machines. The tie-bar-less victory and e-victory series do not have tie-bars, which means that there are no interfering contours in the form of tie-bars during set-up. The mold area is freely accessible, which makes it easier for the setter to work.

Another option is the set-up assistant. The menu-guided tool change program enables inexperienced injection molders to change a tool quickly, safely and easily.

We offer a clamping force range from 28 to 5,500 tons. Even more on request. Our series includes fully hydraulic, all electric and hybrid machines, with horizontal or vertical designs. Depending on the component and customer requirements, we work with you to select the right machine concept for your injection molding contract manufacturing.

If the standard delivery time of our machine is too long, we can offer our fast track or stock machine models. If there is additional cost pressure, there is the option of used machines.

By intelligent temperature control solutions, we mean the iQ flow control software combined with the e-flomo water manifold hardware and the ENGEL e-temp temperature control unit.

iQ flow control automatically regulates pump performance and reduces the volume of water used. This creates constant conditions throughout the injection molding process and increases energy efficiency.

With our self-cleaning package, you can change materials quickly and easily. As little residual material as possible remains in the barrel.

The consumption of the injection molding machine often only accounts for 50% of the energy consumption of the entire system. That is why we look at the energy consumption of the entire system.

You can save energy, for example, with:

  • Intelligent assistance systems

  • Tool temperature control

  • ENGEL energy efficiency packages

Our experts will be happy to advise you on your individual options!

For all-electric injection molding machines, our e-mac is available in an optional slim version. You save up to 240 mm in machine width depending on the size.

In terms of automation, you save space with our HLi solution. The conveyor belt of the system is integrated directly into the safety guarding of the injection molding machine. Peripheral devices can be installed under the conveyor belt. This enables a compact overall system without taking up unnecessary floor space.

The compact cell is similar. This customer-specific automation solution combines minimal space requirements with optimum accessibility.

In addition to the iQ weight control digital assistance system, which compensates for material fluctuations, the recycling package can also be used. The package helps you to process clean regrind on the injection molding machine. This is because both the material feed and the feed area are adapted to these requirements.

Injection molding processes such as sandwich injection molding or the two-stage process also increase the proportion of recycled material in the component.
