Problem solving is key skill to have out on the extrusion blow molding production floor. Whether the problems are out-of-spec parts that the customer won't accepts of they are related to blow molding machine maintenance and downtime, product can come to a screeching halt. That is very expensive. So the more production floor personnel you have out on the floor on all 3 shifts, the better your position is to maximize output, quality and profit. The 7 lesson training program (10-12 hours) prepares your key production floor blow molders to quickly access and solve 95% of the problems that occur.
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

Thank you so much

[@jalaaamasha3628]

Thankkkk you

[@nassaraloui4360]

Good

hello, a doubt what would be the recommended blowing pressure for pieces from 5 to 10 liters (80 grams to 500 grams). And how do I know when I need more or less pressure.

[@ronzx23ulpindo26]

What standard mold temperature for pp?

[@nidhal7184]

Dear Sir,
Good day to you.
Please, is it possible to use PP blow material to use on injection machine? What is the effect on injection machines & molds?
Thnx,,

[@themistercookie8536]

Bruh someone answer his question he been waiting a year.

[@izzatroslan4368]

yes, it is possible. Please be aware that PP have higher melting point than HDPE.

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 injection 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.

I need this dudes voice

[@saravananlatchu8476]

My hot cutter blade is keep breaking off every eight hours, what could be the problem for this to occur.

[@user-nt7yh9vt4r]

may be high voltage applied on the blade

[@saravananlatchu8476]

Owhh kk bro, thnks will check on it.

[@pedroguzman363]

you need to check the amperage in the wires of the blade maybe you need to put lower voltage in the primary of the transformator I put 127 volts and the current go down to half

[@MaheshPatil-dn4ku]

hi sir we are manufacturing of blow molds any requirement pls call me on this no 8000106807. from Ahmadabad Gujarat

[@lxosito]

Or cheap blade, we bought this one that kept breakn on us and found out blade was cheap blade. Also the speed of the hot cutter blade.
