Design office
Emprotec brings its expertise from the design phase onwards.
With more than 35 years' experience in deep drawing, Emprotec can of course work from a drawing you supply, but can also assist your design office with the upstream design of parts, adapting them to the processes and specific constraints of deep drawing in order to optimise tooling and production costs. With this in mind, our design office, together with our in-house toolroom, designs and builds the tool best suited to the technical specifications of a given part.
Tooling
Tooling developed in-house to make production reliable and secure.
To best meet our customers' expectations and essential lead-time requirements, Emprotec develops its own ‘transfer tools’ , taking into account the need for quick tool changes, which has led to standardisation, in particular a constant tool height.
Keen to optimise costs, Emprotec also develops tooling that can perform several operations simultaneously.
The benefit of an in-house toolroom is being able to repair a damaged tool and so return it to service quickly. It also makes it possible to adapt existing tooling to changes requested by the customer.
However well they are carried out, the design and manufacture of a tool still call for a final manual try-out. This step consists of feeding a blank (metal sheet) into the tool to check where it breaks, rubs or slips too easily.
To guarantee a perfect flow of metal, the tool is reworked by hand, which requires great skill, assured by the experience of Emprotec's teams.
Beyond building the tooling, our in-house toolroom also maintains it, thereby optimising its service life without impairing its properties and quality.
Production
Deep drawing allows the material to be heavily deformed, in order to produce thin parts (0.2 to 2 mm) with great depth (up to 90 mm).
They can be formed either with a progressive die or on a transfer press. Emprotec uses the latter technique. Production on a transfer press offers many advantages, particularly in terms of cost and flexibility. A single press is all that is needed to complete the entire drawing sequence, and a part can be modified without having to remake all the tooling.
Emprotec's machine fleet consists of 9 transfer presses from 60 to 240 t and 3 C-frame presses of 15 to 150 t, for a production capacity of up to 1 million parts per month.
Areas served
Emprotec is able to respond effectively to the specific needs of international markets and exports nearly 70% of its production.
It offers flexible logistics solutions and invests in developing robust distribution networks: fast deliveries, real-time shipment tracking, customised stock management solutions to cope with fluctuations in demand…
Emprotec strives to build long-term relationships of trust with its customers that have sites abroad.
Cleaning
Since 2026, Emprotec has had a latest-generation particle cleaning machine in its workshop. Each part reference now has its own tailor-made cleaning programme, adapted to its technical requirements, for optimum cleanliness and consistent quality from one batch to the next.
By carrying out this step in-house, we shorten lead times and become more responsive to your requirements. Less transport, less intermediate handling: the traceability and integrity of your parts are better controlled, and our carbon footprint is reduced.
Quality
From the very beginning, Emprotec's management placed quality at the centre of the customer relationship. Over time, this constant attention was formalised, leading in 2008 to ISO 9001 certification. In 2016, when its certificate was renewed, Emprotec upgraded its quality management system to comply with the requirements of the 2015 version of the standard.
Beyond the guarantee provided by this certification, our teams take care to follow the inspection plans defined with the customer. As a minimum, systematic sampling inspections are carried out on all our production. These inspections can be reinforced according to your requirements and specifications.
