Series parts for vehicle construction and the automotive industry
What they all have in common is that the specifications for sealing parts , and in particular O-rings, must meet the highest requirements. This applies not only to the actual material and the production of the O-ring , but also to the accompanying processes.
Lean management, supply chain management, e-procurement processes, supplier evaluation, strategic development of purchasing processes - we know what you are talking about. We know the processes for implementing new series parts in different industries and have tailored our internal processes accordingly.
For our customers in the automotive industry and vehicle construction, we generally develop products such as O-rings , molded parts , seals or profiles from scratch. Our designers work with you to create a prototype based on drawing parts or your CAD data.
When producing prototypes, you can choose between different prototyping processes: KREMER does not only offer classic 3D printing. You have the maximum freedom to define everything yourself: material, size, geometry, processing such as coating, packaging, delivery. We coordinate all the details of the series parts with you down to the smallest detail, so that in the end the process runs smoothly in your company.
E-Cars Part 1: Dipped PVC Insulation for Current-Carrying Connection Elements
When most people think of electromobility, they think of new drive systems with battery and fuel cell technology. But other innovative technologies play a major role in electric cars. E-cars are equipped with a wide range of on-board electrical systems. High-quality contacts and connection systems are a prerequisite for good electrical conductivity. The cables must conduct the current safely and without short circuits.
For current-carrying connecting elements, KREMER's Krevosol types ensure good insulation of the connection points or for applications with ESD requirements. The dielectric strength of the insulation of 15-20kV/mm speaks in favor of coating with insulating PVC . However, PVC cannot be used permanently above 70 degrees in this application. The achievable layer thicknesses in the dipping process must also be taken into account. We can advise you on the right coatings for current-carrying connecting elements. Contact us!
E-Cars Part 2: PVC coating for handles and hinge supports
With the boom in electric vehicles, we are also seeing an increased demand for coated handles and hinge supports for the internal transport of body parts. Coating with Krevosol standard or special materials offers many advantages:
It protects against corrosion and sharp metallic edges when operating the handles and against damage to the body parts to be protected.
The uniformity of the wall thickness depends heavily on the geometry and surface quality of the metal parts. Rough metallic surfaces tend to introduce air bubbles into the plastisol, which reduce quality. This can only be compensated by slowly immersing the heated metal parts. However, this leads to a greater difference in the wall thicknesses.
The dimensional tolerances can therefore only be determined after a test coating. We have 16 standard colors to choose from. Of course, we offer you a high quality coating and work precisely tailored to your requirements. Do you want to give your metal parts a PVC dip coating? Inquire now!
E-Cars Part 3: Prototype Construction
Sample components of profiles, seals and molded parts can be produced without a great deal of time using our 3D printing technology. 3D printing enables fast, inexpensive and extremely flexible prototype production without tools. When 3D printing, we work with a silicone-like material and various degrees of hardness.
For you, this means that you save time and money and get maximum flexibility. Another advantage: adjustments can be made very quickly in the manufacturing process. Only after the appropriate prototype has been tested and selected are the initial samples made from series tools. The manufacturing process works in a similar way to an inkjet printer - but with three-dimensional results. Find out more about the 3D prototype printing process in the video on our website.
E-Cars Part 4: KREMER calculation tools – also for developers and designers from industry
Online calculation tools from KREMER help you to quickly and easily determine the right sealing solutions! Whether O-rings, stamped parts, water jet cut parts, rubber molded parts or profiles: our website has simple and clear calculation programs for all tolerances of elastomer processing. With just a few clicks and at a glance, you can determine the permissible tolerances for your sealing solution and save yourself the further search in standards or tables.
With elastomer O-rings, the mountability and sealing function depends on the interaction of the tolerances of the inner diameter and the cord thickness and the installation space. Our calculation program takes these two parameters into account for any O-ring dimension. The tolerance is calculated according to DIN ISO 3601-1:2013-11 Class B. We also offer a quick search tool for O-rings . It informs you whether the dimension you want is available as a standard dimension in our warehouse.
Especially with C-parts and high quantities, it makes economic sense to produce the annual quantity in one production run. Many of our automotive customers have production plants abroad - no matter where in the world and in what quantities the series parts, such as O-ring seals or molded parts, are needed - we deliver within Europe or to almost every country in the world .
Or you can use the KREMER consignment warehouse: We store the sealing parts or profiles produced professionally and you can collect them in batches as you need them. Simple, fast and uncomplicated.
