We take you further in just 7 questions

You have high requirements for your plastics technology partner? Very good. Here you can find out in just 7 questions whether and how GIWA can help you.


Question 1

Your plastics partner should supply everything from the idea to series production from a single source?

Yes. A partner with comprehensive know-how is important to me. In this way, I can optimize customer benefits and product costs at the same time.
No. That is less important to me. I have this know-how myself.

Question 2

You want a flexible partner who also responds quickly to last-minute changes or repairs?

Yes. Absolutely! A powerful partner with its own mould construction is an important competitive advantage.
No. That is not worth it for me. If you have to wait longer for parts, that’s just the way it is.

Question 3

You need a supplier who always provides you with the best possible solution at the best possible price?

Yes. There is no alternative to this. I want top quality at a fair price.
No. I can do without delivery reliability, quality and solutions to problems. The price is the only thing that counts.

Question 4

You need someone who can deliver a lot of plastic parts in series?

Yes. Absolutely. I need more than 100,000 of some items per year. Not everyone can do that.
No. I only need small quantities. I can also get that elsewhere.

Question 5

Do you love surprises or are you looking for a partner who delivers consistency throughout the entire value chain?

Yes. My customers demand consistently high quality, functionality and reliability. I expect the same from my partners.
No. Quality and reliability are less important to me.

Question 6

You need someone with know-how in the development and production of very challenging parts or particularly large and heavy plastic parts?

Yes. My plastics partner should be as versatile as possible. This helps me to respond quickly to trends or changes.
No. For me, a simple subcontractor with few skills is enough.

Question 7

Are you looking for a partner who works with you on an equal footing and doesn’t lose their nerve even under stress?

Yes. Constructive cooperation is important to me. The partner’s expertise and experience give me security.
No. I myself am an expert in the development and production of plastic parts.
