Vacuum drying is the best means of drying nylon. Appropriate drying conditions are a temperature of 80-120°C and a vacuum pressure of 1013 hPa. Drying time should be 10 to 48 hours, depending on the pellet water content. Removing pellets from the dryer immediately after high-temperature drying and transferring the pellets to a container could result in oxidation or discoloration. Instead, reduce the temperature to below 70°C under vacuum before transferring the pellets. Figure 1.5 shows an example of a vacuum-drying curve for nylon.

Nylon is a crystalline polymer that absorbs moisture, so be mindful of the following points when attempting to mold nylon.

After opening the bag, nylon pellets will absorb moisture through exposure to the air. The rate of water absorption and the level of equilibrium water absorption are influenced by factors such as the type of nylon, the amount of reinforcement agents (such as glass fibers) added, the shape of the pellets and the air temperature and humidity. Figure 1.2 shows the relative humidity and atmospheric equilibrium water absorption for each nylon type. To find the equilibrium water absorption of reinforced nylons, discount the corresponding equilibrium water absorption value by the water-absorption rate of the reinforcement agent per weight percentage used. Figures 1.3 and 1.4 show the rate of water uptake in representative types of nylon pellets when exposed to the atmosphere. Based on these data, you can see the nylon pellets exhibit a fast rate of water uptake in hot and humid environments. If pellets have absorbed water beyond a certain threshold, using those pellets in a molding process could result in appearance problems such as silver streaking on the surface of the molded product and voids on the inside of the molded product, as well as sacrificed properties resulting from lower molecular weight. Water content of about 0.15% to 0.2% is preferred in nylon pellets used in injection molding. Take the following steps to ensure proper water content levels.

Toray nylon resin is manufactured under rigid quality control standards and packaged in sealed moisture-resistant bags. Therefore, pellets taken from the bag do not need to be pre-dried as long as the pellets are used immediately after opening the bag. As long as the bag is free of damage, the pellets should absorb virtually no moisture during storage. Please handle the pellet bags with care so as to prevent damage to the bag and avoid storing the bags in places with exceptionally high levels of humidity.

Figures 1.9 and 1.10 show drying curves achieved by dryers equipped with a dehumidifier. The dehumidifier removes moisture from the intake air. That dry air is then heated and circulated within the heater as hot air, constantly exposing the pellets to hot, dry air. This method is preferred, as it eliminates risks such as the seasonality referred to above. However, as always, be careful to avoid oxidation or discoloration. Furthermore, dehumidifiers have limited capacity to remove moisture, so remain vigilant in keeping pre-dried nylon pellets as dry as possible.

To recycle sprues, runners and other materials, the material to be recycled must be stored in dry conditions or dried appropriately before injection-molding. The properties of the recycled material will change as the material is subject to thermal history. Furthermore, in the case of reinforced materials, reinforcement agents may be damaged upon exposure to shearing force during the molding process. Generally, recycling results in diminished mechanical strength, while electrical, sliding, sintering and chemical resistance properties remain unchanged. Figures 1.11 and 1.12 show the change in properties in recycled non-reinforced nylon 6 and nylon 66. Similarly, Figures 1.13 through 1.22 show the same for recycled glass-fiber reinforced nylon 6 and nylon 66. See the following for detailed conditions used.

Clearly outline your product specifications, materials, quantity, budget, deadline, and quality requirements before searching for suppliers.

Aside from tensile breakdown elongation, the non-reinforced product maintains nearly 100% of its properties. Test samples show that the glass-fiber reinforced product retains at least 90% of its properties (with the exception of impact strength) when recycled material content does not exceed 20%. However, before using recycled materials, implement rigid controls on the recycled material and determine the appropriate recycled material content level based on sufficient consideration of the products' required properties. Furthermore, during the crushing process, fine particles from the cutter blade could contaminate the recycled material, so use particular caution in compact electrical component applications. Otherwise, fine particle contaminants could destabilize the molding process; be sure to remove the contaminants in such cases. Underwriters Laboratories Standard 746D states that UL-certified materials may contain in-process recycled material of up to 25% by weight. Products containing more than 25% recycled material are to be certified after confirmatory tests conducted by UL.

A hot-air dryer, a hopper dryer or either of these equipped with a dehumidifier can be used in hot-air blow-drying. The degree of drying achieved through hot-air blow-drying is determined by the pellet shape, initial and final water content, drying temperature and the temperature of and relative humidity of the dryer intake air. Figure 1.6 shows the relationship between the state of the dryer intake air and the pellet equilibrium water absorption after using a hot-air dryer on nylon pellets at 80°C. As you can see, the degree of drying achieved is determined by the absolute humidity (water content) of the dryer intake air. Ordinary hot-air dryers and hopper dryers intake air directly from the atmosphere. Therefore the degree of drying achieved is controlled by the relative humidity in the atmosphere, which could easily result in seasonal variance. Drying pellets already low in moisture content could result in higher moisture content, and it may be difficult to achieve sufficient drying in hot and humid environments. To achieve better drying, use a higher drying temperature and a longer drying time. However, note that the extent to which the drying temperature can be raised is limited by the risk of oxidation or discoloration when using high temperatures to perform hot-air blow-drying. Figure 1.7 shows the change in coloration of nylon pellets when hot-air blow-dried at different drying temperatures and durations. Using an ordinary hot-air blow dryer, the drying temperature should be no higher than 80-90°C to prevent oxidation or discoloration. Figure 1.8 shows the hot-air blow-drying curve of nylon pellets. As you can see, excessive water uptake prevents sufficient drying within a short period of time when drying at temperatures low enough to mitigate the risk of oxidation or discoloration.
