Polybridge Training Ltd offer effective training in Plastic Injection Moulding which can benefit all of the following members of staff.

Target Groups.

• Management and Sales staff.
• Purchasing & Procurement staff.
• Designers.
• Setters & Technicians.
• Operators.

All our courses are tailored to the task and can include :

Assessment before and after training - Training Needs Analysis.
Practical training at YOUR site.
Specific Training for your Materials Machines & Processes.
Timing to suit your working patterns
Cost effective 2 or 3 day courses.
• Designed for your skill levels

We carry out on-site training using your processes, your materials and
your products this ensures that the course is tailored to your requirements,
focussing on your companies individual needs and designed to meet current business demands, for the past decade this approach has provided the solution for many companies in a cost effective way, and more importantly increased the efficiency of your key resource - PEOPLE !!

Alternatively we can now offer Off-site courses held at the Engel UK Warwick site, and utilising the latest technology in a modern setting.
Note : subject to a minimum numbers requirement or venue hire supplement.
