Nylon PA610, PA612 toughness ranking
Nylon PA610, PA612 toughness ranking:
Among nylons, nylon PA66 has high hardness and rigidity, but poor toughness. Various nylons are ranked by toughness as follows: PA66＜PA66/6＜PA6＜PA610＜PA11＜PA12.
The flammability of nylon is UL94v-2, the oxygen index is 24-28, the decomposition temperature of nylon is ＞299℃, and spontaneous combustion will occur at 449~499℃.
Nylon has good melt fluidity, so the wall thickness of the product can be as small as 1mm.

Temperature and application of PA66+30%GF nylon raw materials
High strength, special thermal stability, hydrolysis resistance, suitable for automotive parts, mechanical parts, etc.
Used for mechanical parts shields that require high rigidity and dimensional stability.
Red phosphorus flame retardant has long-term stability and excellent mechanical properties.
PA66GF30 is heat-resistant, wear-resistant, high-strength, high-rigidity, and generally has a temperature resistance of about 250 degrees and a decomposition temperature of about 400 degrees.
PA66GF30 is as the name suggests: it is not a model, but a general code for PA66 plastic raw material plus 30% glass fiber.

Acid and alkali resistance of PA610 and PA612 brush wires
In the polymer polyamide nylon brush wire series: PA6 and PA66 brush wires are alkali-resistant, but they are easily soluble in formic acid and cannot be used in acidic environments. PA610 and PA612 are resistant to strong alkalis, weak acids, and are easily soluble in formic acid, and can be used for cleaning in strong alkali and weak acid environments. Polyester PBT brush wires are resistant to strong acids and strong alkalis, and can work in strong acid and strong alkali environments without deterioration. Polypropylene PP is alkali-resistant and acid-resistant. In addition to being corroded by concentrated sulfuric acid and concentrated nitric acid, it is relatively stable to other chemical reagents.
Nylon PA610 resin raw material injection molding cylinder material and strength calculation
Just like the screw, in order to meet the working requirements of the barrel, it must be made of high-quality high-temperature resistant, wear-resistant, corrosion-resistant, and high-strength materials. These materials should also have good machining and heat treatment properties. In addition to 45 steel, 40Cr, and 38CrMoAL, the barrel can also be made of cast steel and ductile iron. The feeding section with a bushing can be made of high-quality cast iron.

Analysis of the reasons why gas is often discharged from plastic molds
Gas is often generated in injection molds, which may be related to the following points:
Some additives in the plastic raw materials volatilize or react with each other to generate gases.
Air in the pouring system and the mold cavity.
