Continuous length Molding

Continuous length Molding

Continuous length Molding

I have an opportunity to produce continuous length molded strips of a TPE. A concept is in hand that appears it will work, however, before investing in technology, I'd like some feedback on existing methods you are using. Anyone care to comment and keep us from "reinventing the wheel"...

Thanks and God bless

RE: Continuous length Molding

If the part is continuous, I would recommend looking at extrusion.  Do a search on the net and you will find many helpful companies.  Good luck.


RE: Continuous length Molding

Depending on the design requirement, for a cheap way you may use pPVC extrusion process.


RE: Continuous length Molding

It cannot be extruded due to the profile

RE: Continuous length Molding


Hmmm...could you explain the profile?  Does it continually change throughout the length?  Keep in mind that there are secondary operations in the extrusion line that can add shapes and modify the contour of the extrusion that may give you what you need.

Good luck,

RE: Continuous length Molding

Picture a timing belt cut and laid open. You can't extrude this because of the teeth, however, we need to do this in contiuous lengths. therefore, contiuous molding...

RE: Continuous length Molding

In this case probably you need to do post extrusion process.
Could you e-mail me your profile design?

RE: Continuous length Molding

We have done some rubber parts like this where the ends of moulds were kept cool to prevent cuering and after process joining to get continued length .in this way we could get length of belt like job even 25 ft.long and even endless. it can be tried in your case

eBook - Rethink Your PLM
A lot has changed since the 90s. You don't surf the Web using dial-up anymore, so why are you still using a legacy PLM solution that's blocking your ability to innovate? To develop and launch products today, you need a flexible, cloud-based PLM, not a solution that's stuck in the past. Download Now
White Paper - Using Virtualization for IVI and AUTOSAR Consolidation on an ECU
Current approaches used to tackle the complexities of a vehicle’s electrical and electronics (E/E) architecture are both cost prohibitive and lacking in performance. Utilizing virtualization in automotive software architecture provides a better approach. This can be achieved by encapsulating different heterogeneous automotive platforms inside virtual machines running on the same hardware. Download Now
White Paper - The Criticality of the E/E Architecture
Modern vehicles are highly sophisticated systems incorporating electrical, electronic, software and mechanical components. Mechanical systems are giving way to advanced software and electronic devices, driving automakers to innovate and differentiate their vehicles via the electric and electronic (E/E) architecture. As the pace of change accelerates, automotive companies need to evolve their development processes to deliver and maximize the value of these architectures. Download Now
