Excuse me, what is the injection temperature of abs plastic?
Molding temperature: 200-240℃?

Drying conditions: 80-90℃ for 2 hours?

Molding characteristics:

1, amorphous material, with medium fluidity and high hygroscopicity, must be fully dried. Plastic parts with shiny surface should be preheated and dried at 80-90 degrees for 3 hours.

2. It is advisable to adopt high feed temperature and high mold temperature, but it is easy to decompose when the feed temperature is too high (decomposition temperature > 270 degrees). For high-precision plastic parts, the mold temperature should be 50-60 degrees, and for high-gloss heat-resistant plastic parts, the mold temperature should be 60-80 degrees.

3. In order to solve the problem of water entrapment, it is necessary to improve the fluidity of materials, adopt high feed temperature, high mold temperature or change the water level.

4. If heat-resistant or flame-retardant materials are formed, after 3-7 days of production, plastic decomposition products will remain on the surface of the mold, causing the surface of the mold to shine, so it is necessary to clean the mold in time and increase the exhaust position on the surface of the mold.

Extended data:

Features:

1, good comprehensive performance, high impact strength, good chemical stability and electrical properties.

2. It has good weldability with 372 plexiglass, can be made into two-color plastic parts, and the surface can be chrome-plated and painted.

3, high impact resistance, high heat resistance, flame retardant, reinforced and transparent.

4. the fluidity is a little worse than HIPS, better than PMMA and PC, and the flexibility is good.

Uses: Suitable for manufacturing general mechanical parts, wear-resistant parts, transmission parts and telecommunication parts.

According to different needs, you can choose the following adhesives:

1.G-977: One-component soft elastic shock-proof adhesive, which is cured at room temperature and resistant to high and low temperatures, and cured at different viscosity bonding speeds of several seconds to several hours;

2.KD-833 instant adhesive can quickly bond PC plastic in a few seconds or dozens of seconds, but the adhesive layer is hard and brittle, and it can't be soaked in hot water above 60 degrees;

3.QN-505 is a two-component adhesive with soft layer, which is suitable for large-area bonding or compounding of PC plastics.

4.QN-906: Two-component high-temperature resistant adhesive:

5.G-988: One-component room temperature vulcanized rubber. After curing, it is an elastomer with excellent waterproof and shockproof adhesion and high and low temperature resistance. If the thickness is 1-2mm, it will initially cure in about 10 minutes, and basically cure in 5-6 hours, with a certain strength. It takes at least 24 hours to be completely cured. A component that does not need to be mixed can be used after extrusion and allowed to stand without heating.
