Tips From a Manufacturer's POV: #2 Prototype VS Serial Production Pricing

Updated: Apr 16


As manufacturers, we accompany projects in various stages of development. Pricing for a model will be fundamentally different from the pricing of a part of a serial production. In a prototype production, various parameters are included on the price, which in serial production the relative part of these parameters will usually be negligible.


What's included in the price of a complex prototype?

 

primacy

In most cases, the first time we come across a part that needs to be produced, is at the request for quote stage. In the production of very complexed parts, even the quotation stage can take several hours, up to a few days. Although there are similar working methods and concepts, the production of each part requires creativity, thinking outside the box and experience - data that is also included in the price.

Basically, already at the stage of the price offer, we use a lot of imagination, in order to understand how the process will finish with a drawing and the complex 3D file that we looking at.

 

Full and exclusive attention to the prototype part

When a prototype part is manufactured, both our employee and the machine itself are almost exclusively associated only with the production of the specific prototype. That is, as long as there is a production process of the prototype which can take several days/weeks, both the machinist and the machine will exclusively work one the specific prototype project.

·

CAM design 

in some cases, designing a complex prototype part in the CAM software can be very long and sometimes even longer than the production time.

 

Set-up

the phase between the planning and the start of production, the preparation of the raw materials, the measuring of the tools and the clamping fixtures on the machine. This step can take several days in a very complex part. If work with several technologies is required, the set-up time will be more significant.

 

Raw material 

if it is a large part of an expensive polymer or metal, then the price will be significant, if it is a small part, the price will usually be relatively negligible. This parameter will be particularly prominent in situations where we are required to buy a minimum amount of the raw material from the supplier.

 

Tools 

end mills, drills, holders or other special tools - the amounts can reach thousands of shekels in a project with special features. We will also take into account the likelihood of tool wear and breakage depending on the processed material, and the required precision. This parameter will be taken into account in the same way for a mass-produced product as well as for a model.

 

Additional treatments

Most standard treatments, such as anodizing, passivation,hardening, etc., will be priced per portion. That means that the price for one unit and for 200 units can be the same. We emphasize - we do not perform addition treatments at our factory, therefore the price of the treatment will be determined by the external supplier with whom we work.

 

Quality Inspection

There are two levels of quality control. Inspection during production - for example before replacing a blade, or while the part is still placed in the machine - we will check the critical dimensions. Final inspection - what will finally be seen as a COT report - dimensions that will be measured by accepted measuring equipment when the part has finished all its processing stages, including supplementary treatment.

In the final inspection, there is a significant difference between a model and part of a series - in series, percentages of all the parts produced (on demand) are measured, while for a prototype we will perform a full test of all the models produced. Such a test can take many hours and of course it is also included on the final price for the customer.
