Many people have reported that the lifespan of plastic raw material testing instruments is quite short when using them. There are many reasons for this, possibly related to quality, but a significant reason is that after long-term use, regular maintenance and care are often neglected.Every machine requires maintenance, and high-tech products like plastic raw material testing instruments especially need proper care and maintenance. Therefore, to extend the equipment's service life, it is essential to perform maintenance and care after a period of use.Maintaining it is not very difficult. After some period of use, only the main components of the equipment need to be inspected and serviced. It is not necessary to check every single part, but if the device has been in use for more than two years, a thorough inspection is recommended. This allows for the replacement of damaged parts and extends the usage life.
