Finishing
Most of the technical products leaving our facilities require some extra treatment after the moulding process. We offer all post-processing steps in-house
Deflashing
As thermoplastic resins are engineered for more demanding applications, there is a tendency for these resins to run like water through a mold and that creates flash. Deflashing or deburring techniques using water, grain, air and numerous other techniques have been developed by Helvoet to remove this flash and maintain the integrity of the parts.
Flat Grinding (Single/Double)
Altough it is always the goal to get ready-to-use products straigth out of the mould, tighter tolerances mean higher perfomance for our customers. Maintaining thickness capability at 0.002 mm requires a secondary process: flat grinding or lapping. Helvoet has delivered close to 500 Million parts that have used this technology ensuring micron precision.
Printing
With various printing techniques and methods Helvoet can help you mark, identify, and trace your products. From manual tampon printing up to continuous motion high speed printing in two colours we can deliver your needs.
Post-Curing
Engineered resins like PPS, phenolics and rubber, require an aging process called post-curing. This process removes stress, helps guarantee dimensional stability and removes final volatile materials that are inherent. Helvoet has numerous post curing profiles that have been developed for each and every one of these materials.
Ultrasonic Welding
Assembly techniques like ultra-sonic welding are used when you have two components that are made from the same material, but can't be made as one part due to geometry. Helvoet uses this as a fast, accurate, clean and leak tight method of assembly.
Laser Welding
Laser welding, also called transmission welding, is another technique used establish a reliable bond of thermoplastic materials. A focused laser beam goes through a transmissive layer onto an absorption layer and as it is turned into heat energy the plastics melt and form a stable connection. Helvoet can assist you with selecting the right materials and process for your part.
Washing / Rinsing
Helvoet measures their products in microns and understands that contamination can occur in the numerous processes. Thus we have developed a sophisticated washing and drying process to remove contamination and ship products that meet your demanding requirements.
Coding (RFID)
At Helvoet we provide different ways to trace a production and in many applications RFID or Coding is used. Having 100% traceability and full transparency in the assembly process gurantees that we can deliver the highest quality parts to you, our customer.
Filling
With experience in both dry powder and liquid filling we can offer you a one stop shop solution.
Especially in our health tech business we are filling molded primary packaging and diagnostic products with desiccant granulate or with liquids to offer additional benefits to our customers.
Leak Testing
If a product like an ABS System leaks you will have a problem. That request you to have 100% leak-testing before you assemble. Helvoet's expertise in managing and monitoring the flow of media (fluid, air, gas), has given us a wide variety of experiences developing custom leak-testing equipment and integrating it in our production processes.
Vision Inspection
Did you know that 100% visual inspection by a human is only 80% accurate? Is that good enough for your products? Inline cameras have been placed at many locations throughout the manufacturing process to ensure the quality of your products.
Measuring
If you can measure it you can improve it! Measuring in nanometers and microns is becoming the norm in industry today. Helvoet's measuring capability includes state of the art equipment such as interferometers, air gauging, video measuring, contour roughness, 3D whitelight and other contactless measuring devices.
