Trouble Shooting
Plastic products are required to pass through a large number of different processes in their manufacture. However, since these components contain organic polymers, it is important to give consideration to usage environments.
This site describes the problems for which customers sought assistance in the past and offers reference material for a variety of different situations.
Molded Part Cracking
Cracks in ABS resin molded products can be classified into three main types by visual observation of the fracture (crack) surface: "ductile fracture", "brittle fracture" and "fatigue fracture". The phenomenon of destruction provides important information for investigating the cause and taking countermeasures.
Molding Defects
We will introduce molding defect problems during ABS resin molding.
Problems can occur with one or a combination of factors such as product design, resin selection, and molding conditions.
Please understand the details of the defect by phenomenon from the items below.
Weathering
When used outdoors or under indoor fluorescent lighting, ABS resin may cause discoloration or deterioration of certain physical properties during long-term use. Here, we will explain the phenomenon of weather resistance (light) deterioration.
The problem of weather resistance in ABS resin is caused by photodegradation of the polybutadiene component. Due to this deterioration, the role of rubber that expresses impact strength disappears. It is also characteristic that this deterioration is limited to the surface layer only.
Painting Defects
ABS resin is the easiest resin to paint and is widely used in painting specifications.
However, coating defects may occur depending on grade selection, molding conditions, paint, thinner, coating method, etc. Please take a look at the photos of the defective phenomenon and use it as a reference for troubleshooting.
