What is the procedure for projects at G.W.P., and can I have an overview of a typical project timeline?

an example of a projects timeline can be found at our download pages under "How-we-do-business" (PDF).

What you need for a bid?
For us to make a binding offer, we require DIN-compliant technical drawings (2-D and 3-D), if possible as a CAD file with all the necessary information, as well as the desired batch sizes and annual quantities.
Please inform us of any particularly critical functional dimensions, special materials or special requirements. In addition, we require a fixed project name as well as unique drawing numbers. Please also note our "RFQ check list" (PDF).
We do not have any 3-D models or CAD drawings. Can you create these for us?
If you do not possess any CAD drawings or 3-D models, we will be glad to create them for you at an economical price. We would also be glad to digitally convert old drawings into CAD formats. G.W.P. has its own CAD center to do this. 
Would you be able to sign a confidentiality agreement or NDA?
We are willing to sign such an agreement concerning the nondisclosure of information of any kind. However, you should first submit an initial request to determine whether collaboration is worthwhile. Sensitive data can be provided after it is that probable that we will prepare a bid.
Do I have to correspond with your Chinese branches, and who is my contractual partner?
Your sole contractual partner and contact is G.W.P. AG in Germany. The highly competent team in Berlin is responsible for all technical and business needs. All oral and written correspondence can be conducted either in German or English.
Where should I send my query or order?
Send us your queries, orders, and all other correspondence to our Berlin marketing office, ideally by e-mail at: sales@gwp-ag.com
Attachments of up to 10 MB are possible.
When can I count upon receiving a bid from you?
First we need to review your query for completeness (drawings, required information). If any information is missing, we will quickly contact you. Then we will review the project for feasibility, process stability and manufacturing capacity, and will obtain offers from qualified suppliers and contractual partners if necessary. We will then prepare a detailed and binding offer on this basis. You will usually receive our bid within 10 days.
What is the minimum number of parts that I must except for series production?

That depends on the manufacturing process, the materials, the part, and the amount of finish work. Diecasting becomes economical starting at a batch size of about 300 pieces or 500 kg; plastic injection molding becomes economical starting at about 1,000 units or 25 kg.
For lathed or milled parts, the minimum number of units is approximately 3,000 units for small parts, approximately 1,000 units for medium-sized parts, and about 100 units for large parts. The minimum number of customer-specific aluminum extruded profiles depends on the profile, but it is usually about 200-300 kg per profile.


Do you also manufacture individual parts and small batches?
We use our rapid prototyping service for very small batches. At present, we offer the procedures of metal lasers sintering, selective laser sintering, stereolithography (SLA), as well as all machining processes and wire eroding (EDM).
How long is your bid valid?
Our bid is binding for 15 days, and we can agree to longer binding periods depending on the project. If the situation regarding raw materials is problematic, we retain the right to adjust prices at short notice.
I have not yet received any confirmation of receipt. How can I make sure that my query/order is being processed?
Once we receive your e-mail, we will automatically send you a short status message. Usually, we contact you within the next two days to inform you about the status. In response to queries, you will receive either a bid or rejection after they are reviewed. After an order is submitted, you will receive an order confirmation with all of the relevant information. If this does not occur, please call our G.W.P. team at +49 30 757744-0 to find out if your query or order has been received. To prevent the duplication of records, please do not send us a second copy of your order without identifying it as such.
