Six standards for testing the quality of antifreeze bucket mould

Injection bucket for the plastic bucket are mostly used for the storage and transportation of various liquids. They have good characteristics for special dangerous goods packaging. They are not brittle, non-rusty, lightweight, and have good oil and strong corrosion resistance. Packing of dangerous goods with thermal insulation, moisture resistance, pressure resistance and corrosion resistance. Its materials are mostly made of polyethylene, polypropylene, polyester and other plastics by blow molding, injection molding, blistering, and rotomolding. They are mostly used to hold liquid and solid items in the chemical, pesticide, pharmaceutical, food, hardware, electronics, and mechanical and electrical industries. Do you know the standards for testing antifreeze buckets mould?

1. High temperature resistance test The
plastic bucket will be put into a room for 3 days. The temperature of the room was maintained at 90-95 degrees Celsius. After cooling, the surface of the plastic bucket should not be damaged, blistering or deformed. The moisture absorption of the raw materials is less than 0.01 to ensure that the box structure does not become brittle or deformed.
2. Lifting and dumping test
Place it in the calibration environment for more than 12 hours, add a load of 120 kg, and continuously lift, dump, and lower it for more than 2000 times without cracks. And the static and static plastic buckets are tested on the inclined surface with an inclination angle of 100. The plastic buckets do not fall.
3, UV protection and hardness test
From the perspective of engineering plastics, the UV protection component in the raw material has a great correlation with the hardness of the plastic mold. In addition, the UV intensity is different in every corner of the world. And in the same place, different colors respond to ultraviolet light differently.
4. Wall thickness of the mold
From the perspective of engineering plastics, the wall thickness of the mold is not the main reason for the toughness of the mold. The raw materials used, UV-resistant ingredients, molds, and injection molding equipment are all related. For most customers, the quality of a plastic bucket is not the wall thickness but whether the plastic bucket can pass different test conditions. design.
5. Anti-corrosion test
When testing the anti -corrosion performance of the plastic mold, put the mold in corrosive chemicals, and then keep the temperature of the corrosive chemicals at 75 degrees Celsius and immerse for 48 hours. The mold should not have any Cracking, blistering or deformation occurs
6. Resistance to cold and heat
Working temperature: -30 ℃ ～ 50 ℃. Destructive test: -30 ° C to 110 ° C (softening temperature). Detailed description: The plastic bucket will be refrigerated at -18 ° C for 12 hours. Then, a 65mm diameter iron rod with a weight of 5kg will be used to hit the injection point of the plastic trash can 3 times from a height of 1m. After the low temperature test, the mold should not crack or deform.
