Shrinkage rate nylon 66

Its viscosity is sensitive to temperature changes. The shrinkage rate of PA66 is between 1% ~ 2%. The addition of glass fiber additives can reduce the shrinkage to 0.2% ~ 1%. Shrinkage in the flow direction and the flow direction of the vertical difference is larger.

Nylon 66, 260, 500 Mold temperature affects the cooling rate. part molded of Zytel® 101 L.7 As the mold temperature rises, the shrink rate also increases. 27 Jan 2020 Even the material's shrink rate needs to be considered. 69, PA(Nylon)66, PA( Nylon)66 Dupont Zytel 101L NC010,Natural, Injection molding 

Nylon 66, Zytel® ST801 is an unreinforced, super tough polyamide 66 for injection molding and extrusion. It offers outstanding break resistance over a wide temperature and humidity range and high productivity.

An important difference between Nylon 6 & 66 is mold shrinkage. Nylon 6’s lower mold shrinkage adds reliability to final part dimensions which is beneficial whilst Nylon 66’s greater mold shrinkage, as it is exposed to cool air and solidifies, means the material’s shape changes more after processing, which must be accounted for.

To determine the proper shrink rate for a given polymer the tooling engineer must consult the manufacturer of the material. Shrinkage varies not only with the  Ultramid®. Polyamide chemical structure melting point [°c]. Ultramid® A. 66 basis hexamethylene diamine applied stress against the load-cycle rate achieved in each case (Fig. 13). Products based on Ultramid® T show lower shrinkage in. In higher shrink materials such as acetal and nylon, the post-mold shrinkage can be significant. If the regions of the part shrink unequally (called as warpage) stresses are created within the part which, depending on part stiffness, may cause the part to deform or change shape and hence leading to cracks in parts during long term use.

Resin Mold Shrink Rate. All resins have different shrink rates depending on resin family, amorphous vs. crystalline materials, mold design, and also depending on processing conditions (cycle time and temperatures) as well as part design (shape and wall thickness).

For PA6 products without additives, its shrinkage is between 1% and 1.5%. Glass fabric can be added to reduce the shrinkage rate to 0.3% (but the direction and the process is even slightly higher vertical direction). Shrinkage of the injection molding is mainly affected by the material crystallinity and moisture absorption. Easier to process than Nylon 6/6 (castable), may be reaction injection moulded. Has lower mould shrinkage than Nylon 6/6 with good fatigue resistance. Useful improvement in stiffness can be obtained by inclusion of glass fibres, unlike acetals. Disadvantages. Highest rate of water absorption and highest equilibrium water content. Nylon 66, Zytel® ST801 is an unreinforced, super tough polyamide 66 for injection molding and extrusion.
