After leaving the injection molding machine, nylon products need to go through a processThe baptism of water and fire. The traditional water boiling humidification process was once a necessary path for toughening treatment of nylon materials such as PA6 and PA66. In the steam filled workshop, workers need to immerse nylon parts in boiling water and steam for several hours, then painstakingly remove and wipe off any remaining water stains and white spots on the surface.

This process not only consumes a large amount of energy and manpower, but also leads to significant fluctuations in product moisture content and unstable quality. After boiling water, the surface of nylon parts often retains scale crystals, especially at corners, and even small partsUnable to clean thoroughlyIn autumn and winter, even after going through such tedious processes, products may still become brittle and prone to breakage.

The four major pain points of traditional water boiling method for nylon products:

1. The problem of surface defects.Nylon products treated with water or steam often have white spots, water stains, and crystal residues on the surface, especially in the corners of structurally complex parts, forming difficult to remove white dirt. Before shipment, the factory has to organize a large number of manpower for wiping, and for small precision parts, the cleaning effect is even more difficult to guarantee.

2. Hidden dangers of uncontrollable moisture content.Nylon has a long moisture absorption time in natural environments, and traditional boiling methods are difficult to accurately control the moisture content. Nylon molecules are hydrophilic molecules, and the higher the proportion of amide groups (such asPA6、PA66）， The stronger the water absorption. The unstable moisture content leads to fluctuations in the mechanical properties of the product, and even after careful handling in autumn and winter, the product may still experience fracture complaints when it reaches the hands of customers.

3. High energy consumption and environmental costs.Boiling or steaming requires continuous heating of a large amount of water, which consumes an astonishing amount of energy. What's even more serious is that the treated wastewater contains additives dissolved from nylon products, which can cause environmental pollution if discharged directly, and the construction of wastewater treatment facilities will increase the additional burden on enterprises.

4. Intensive manual dependence.From soaking and salvaging to wiping and drying, every step cannot be separated from manual operation. If a medium-sized factory has50-100 injection molding machines require a large amount of manpower for the post-processing process alone. In today's world where labor costs continue to rise, this has become a key factor restricting the competitiveness of enterprises.

The technological breakthrough in moisture regulation of nylon products: the core innovation of nylon humidification and toughening box:

The nylon humidification and toughening box of Ningbo Edson Instrument passes throughTriple technological innovationBreaking through the traditional boiling process:

1. Precise control of temperature and humidityThe device adopts a microcomputer control system, which can be used inAccurately adjust the temperature within the range of 65 ℃ to 100 ℃, with a humidity control range of 60-95% RH and a fluctuation of only ± 0.5 ℃. Real time monitoring through PT100 platinum resistor ensures uniform and stable temperature and humidity at all points inside the box1℃.

2. Intelligent toughening system.The TFT color touch screen is equipped with an intelligent control system that can store 100 programs, with a maximum of 100 steps and 999 segments per program. The device supports one click start, and the operator only needs to set the parameters. The system automatically completes the entire process of humidification, insulation, and drying, and ends with an automatic shutdown alarm.

3. Closed loop water-saving design.Innovative equipment processes tap water through a water purification device and inputs it into an electric steam generator to generate clean steam. Using a forced circulation fan (stainless steel long shaft centrifugal fan) to ensure uniform air flow inside the box, the steam utilization rate reachesMore than 95%. Compared to traditional boiling methods,Water saving rate reachesMore than 70%And there is no wastewater discharge throughout the entire process
