Extend the lifetime of your machine by 10–15 years
We specialize in retrofitting injection molding machines by replacing obsolete control systems with modern KEBA control solutions.
Your machine mechanics remain unchanged – only the control system is upgraded
Our focus is purely on control systems.
We do not rebuild machines – we modernize their “brain”.

Why Control Retrofit?
• 30–50% of the cost of a new machine
• Short and predictable downtime
• No mechanical rebuild

• Existing mechanics and hydraulics preserved 
• Familiar machine with a modern control system
• Long-term spare parts availability

The Problem

Your machine still works – but the control system doesn’t.

Many injection molding machines are mechanically in good condition, but their original control systems are outdated, unsupported, or unreliable.
Typical issues we see:
• The original controller is no longer supported by the manufacturer
• Spare parts are unavailable or extremely expensive
• Random faults and unstable production behavior
• No interface for modern peripherals or systems 
• Increased risk of unplanned downtime
The problem is not the machine.
The problem is the control system.

Our Solution

Our focus is purely on control systems.

We remove the original control system and replace it with a modern KEBA control platform, fully adapted to your existing machine, hydraulics and application.
Scope of work:
• Removal of the original control system
• Installation of KEBA PLC, HMI and I/O modules
• Software adaptation to machine logic and sequences
• Integration with existing machine components
• On-site commissioning and functional testing
• Operator training and handover
The retrofit is engineered specifically for each machine.

Why Retrofit Instead of Buying a New Machine?
Buying a new machine
• High investment costs
• Long delivery times
• Operator retraining required
• New production risks
Control system retrofit
• 30–50% of the cost of a new machine
• Short and predictable downtime
• Existing mechanics and hydraulics preserved
• Familiar machine with a modern control system
If the mechanics are in good condition, a retrofit is often the most economical solution.

Machine Brands We Retrofit

Our focus is purely on control systems.

We retrofit injection molding and rubber machines from all major manufacturers, regardless of brand or year of manufacture.
Our experience includes machines from:
Engel, KraussMaffei, Haitian, Windsor, Desma, REP, MAPLAN, LSMtron, HPM, Hemscheid, Milacron, Battenfeld, BMB, MIR, Husky, Ettlinger, Biraghi, Fahrbucher, Tederic, Wickert, Billion, Arburg, Diefenbacher and many others.
Each retrofit project is evaluated individually based on the machine configuration and application.

Why KEBA?
KEBA is a proven industrial control platform widely used in injection molding applications..
Key advantages:
• Long-term availability of hardware and spare parts
• High industrial reliability
• Open and flexible architecture
• Well suited for machine retrofits
• Scalable for future extensions
KEBA is not an experiment – it is an industrial standard.

Optional Upgrade: Servo Pump Retrofit
During the control system retrofit, we can optionally integrate a servo pump system, depending on the machine configuration.
Benefits:
• Reduced energy consumption
• Smoother and more stable machine operation
• Optional upgrade, evaluated case by case
Servo pump integration is offered as an add-on, not as a mandatory part of the retrofit.

Retrofit Project Workflow
1. Machine evaluation and definition of retrofit scope
2. Engineering and preparation
3. On-site installation of the new control system
4. Commissioning, testing and optimization
5. Operator training and project handover
If required, production can continue between project phases.

Is This Retrofit Right for You?
This solution is suitable if:
• The machine mechanics are in good condition
• The control system is obsolete or unsupported
• You want to extend machine lifetime without buying a new machine

This solution is not suitable if:
• The machine has major mechanical damage
• A complete machine rebuild is required

Get a Retrofit Evaluation
Send us your machine details and we will evaluate the retrofit potential.
Typical information we need:
• Machine brand and model
• Year of manufacture
• Current control system (if known)
• Country / location of the machine
• Wiring diagrams (if available)
• Hydraulic diagrams (if available)
