Implementing a comprehensive training solution for your blow molding company will allow you to have a continuous resource of highly qualified technicians to promote from within or to fill in on the production floor as needed.
Train production personnel, supervisors and managers to understand the basics of extrusion blow molding technology, plastic behavior during the blow molding process, machine set-up for optimal production runs and common problem solving situations. The course will prepare your blow molding personnel to:
1. Develop a working knowledge of blow molding machinery
2. Evaluate and improve operating procedures
3. Recognize processing conditions that affect quality
4. Analyze and solve practical blow molding problems
Lesson 1 - The Process and the Equipment
Lesson 2 - Plastic Behavior
Lesson 3 - Extrusion Blow Molding Operating Controls
Lesson 4 - Operating Procedures - Start-up, Operation, and Shutdown
Lesson 5 - Part Quality and Problem Solving - Part 1
Lesson 6 - Part Quality and Problem Solving - Part 2
Lesson 7 - Parison Programming

I'm working with the local civil protection director to make a prototype of a torpedo style rescue floatation device to be donated and mounted on natural wood posts at our most historically dangerous beaches.
These torpedoes are abusively priced ($150 USD), not available locally here in México and not available in all-natural materials but I'm working to change that.
We need a local bioplastics supplier with materials well suited for this purpose with sheet plastic that can be manually heat-formed over a mold. And for a much larger scale impact, we need an estimate of the cost of mold that could be used with recycled plastics, bioplastics and biodegradable plastics also to blow mold them for us. If we can raise the funds to pay for the mold ourselves, the devices can be relatively very inexpensive which will make them very accessible and help save lives everywhere they're used.
