How to Make the Crate a Long-Life Span and Reduce the Cost

Look at bad crates and how they fail, adjust the design to reduce the weaknesses which cause the failures.
I expect corners and handles are the general failure points, or splitting in the middle of thin flat unbraced areas like the bottom.
Good control of the material and molding process is also vital.

Rubbish!

I'm so sorry if my words make you feel uncomfortable.

and this well thought out erudite comment is based on what? Could you possibly quote a source?

Here is just one article indicating the growth of plastic usage in the packaging industry.

I personaaly have worked in the petrochemical industry for many years and can assure you that there are many new plants coming on stream to cope with this increased demand.

Not every CR4 reader works in the petrochemical industry, therefore not every CR4 reader can be expected to know that, even if interested.

Well, if you do not "know that" and you are not interested why did you feel the urge to make such a rude comment in your first post?

Rubbish!

Touchy today, aren't we?

I never heard you reply like this! Bad pint in the Bothy.

I just quoted an Injection molding design and development project for a small to mid-size Champagne producer. He is serious, he uses 1.2 million cardboard cases internally each year and has to replace them due to their unsuitability for the process. Wants to go to foldable plastic cases due to warehousing needs for empties etc during the process of riddling. So would you develop a plastic solution that may last 5+ years or keep producing cardboard cases?

A major wine producer has just been shown my design and he sells 78 million cases of wine per year. These are not bullshit numbers to impress you but there is a need for a better packaging system. It may not be plastic but it is a solution to be explored. Personally I need work, feel I can perfect the design that has already turned these guys on, may even get a patent and may even get a royalty?

Wouldn't that be a fix for bobbing on the bring of bankruptcy while working harder than I have ever worked due to the power of the RMB and Yuan that eroded my business over the last 10+ years?

I wonder what the cardboard box factory workers will do when their plant closes?

And, you don't see thousands of tons of cardboard box bits floating on the world's oceans either. That's all plastic, baby.

Now, don't get me wrong. I ran an injection molding facility for Motorola back in the 80's. There's a place for it, but it isn't going to save the environment.

And, at the end of the day, the OP is just a huckster for the Chinese plastics industry. Is that industry really your friend?

If you take a look at the OP's past posts, as I have, you will learn that her/his goal is simply to sell thermoset plastic products.

All of this drivel should be in the commercial section.

I believe that the comment of PWSlack in his post #2 is spot on and even simply eloquent.

It is rubbish!!!

Hello Lynlynch,

PW.Slack and you are correct and saw thru the OP quickly. A front for a Chinese shop?

All I can do is keep trying to be sincere in my replies!

As to the new plastic case, it has a place in addressing the economics of doing the particular business but an environmental impact report would be a good idea before I proceed.

Thanks for keeping me on the straight and narrow.

I could mold the case from recycled milk containers (green business?), silkscreen your pretty lady on one side of the case and Sinosiya on the other, now that would really be 2 faced, creating rubbish to float in the mid Pacific and flying the green recycle flag!

But with those pictures on the floating debris, any sailor floating by would probably pick up the trash. So that would solve the trash floating in the ocean problem.

We all have to earn a living.

What's the difference between this OP's business and anyone else on here? There appear to be lots of people out there doing very well with apparently little or no knowledge of what they're on about so surely we can help someone with a "proper" question, even if they do have a business selling thermoset plastic products. (Yes, I do remember the "bakelite" question).

2tinker - why not sell this guy your design? Could be a marriage made in heaven.

Hello M Daniels,

It would be cool to sell the design but I have seen this student turn into a professor in just a few posts. So he has probably deciphered my design concept and it is being built in China as we speak with a T0 date of 8-20-2010 and T1 shortly after. What do you think?
