Processing Technology Injection Molding
Description The engine in a modern car has to fulfill severe design criteria, amongst others a low fuel consumption and a low exhaust emission. One of the consequences of this is the presence of high torsional vibrations in the drive train.
These vibrations can be dampened with a dual mass flywheel, in this case called a
abcdefgmechanical torsion damper (MTD).
The MTD should be produced at a targeted price with as low as possible a weight. This is the moment where the application of plastics play a favourable role. The requirements on the plastic were severe:
- high stiffness at high temperatures
- low creep
- high resistance against fatigue loadings
- resistant against the applied greases
- low wear
- reasonable price

The only plastic fullfilling all these requirements is:

Processing Technology Injection Molding
Description Lower component costs by replacing metal in hot oil environment With the help of Stanyl, this single-piece injection-molding consolidated two component parts with extra integrated functionality and a reduced part weight. The material needed to provide both structural integrity for the balance shaft cover and the wear and abrasion resistance required by the guide. Both functional areas of this single component face continuous use temperatures of up to 310ºF (155ºC). Stanyl was able to deliver on these requirements! The engine's balance shaft smooths engine operation, reducing noise and vibration versus other four-cylinder engines. The shaft's cover, previously manufactured using stamped sheet metal, must maintain its strength, stiffness, and rigidity while exposed to engine oil during operating and heat-soak conditions. Integrating the two functional components also reduced the number of fastening points required to secure the chain guide, allowing for further material and assembly cost reductions.

Description Syanyl's wear resistance extends the performance lifetime Stanyl has set the performance standard for automotive chain tensioners for many years. In two-wheelers, the drive chain needs to be under constant tension and employs a chain tensioner that is subject to similar severe wear conditions. By using Stanyl, the lifetime of the tensioner is extended up to seven times compared to PA66. Not only does Stanyl have excellent wear and friction properties, it exhibits high resistance to oil and to fatique loadings and has low creep behaviour.

Description Looking to replace metal, consolidate parts, and reduce system costs in their chain tensioner Schaeffler turned to Stanyl TW341 from DSM Engineering Plastics. The chain tensioner is used in high volume engines that are supplied to Ford Motor Co. Throughout the evolution of the powertrain, Stanyl has been and remains the best material for tensioners. Stanyl offers better wear performance than high molecular weight PA66, provides the highest safety and durability factors, and allows for the reduction of noise generated by the chain. In addition, it has the best fatigue and creep resistance at temperatures and better fatigue resistance than PA66. Stanyl is an extremely high performance material delivering excellent wear and friction properties, high stiffness at elevated temperatures, high fatigue resistance, low creep behavior, and retention of properties after oil aging. DSM provided structural analysis on the tensioner for Schaeffler as well as technical and design support to help successfully replace metal and optimize the design. DSM has the application experience and tools to help optimize designs for tight spaces. Application and design engineers take the time to understand the system, know what is important, and how this affects the loading and performance of the structural parts.

Processing Technology Injection Molding
Description Stanyl®'s superior mechanical and thermal properties make it an outstanding material choice for solving the locking hub problems caused by the loads of increasingly powerful engines and the heat generated in anti-lock braking systems of sport utility vehicles. By switching from nylon 66 to Stanyl® polyamide 46 the manufacturer was able to extend the life of its four-wheel drive hub. The plastic components inside the locking hub must withstand heavy loads, high temperatures, and abusive conditions. Under certain circumstances, the hubs manufactured with 66 nylon components had problems engaging. In addition, the short, efficient stops of anti-lock brakes generate heat above 400ºF that caused nylon 66 parts to creep or even melt. Stanyl®'s melting point of 563ºF is able to withstand heat and is a more cost-effective material than other very high temperature resins. Because Stanyl® exhibits similar shrinkage to nylon 66 the manufacturer saved money by not having to do much retooling. In addition, Stanyl® reduced cycle times by 20 to 30 percent, providing further savings.
