Technical problem nine, Can the color of plastic products be changed without stopping the machine during mass production?

Can the color of the plastic product be changed and the production can continue without stopping the production of large quantities? This question was recently raised by a customer during follow-up production. To answer this question, we must first understand the principle and process of plastic production.

The production of plastic products is produced by adding plastic materials to plastic processing equipment (injection molding machines, blow molding machines, extrusion blow machines, etc.) through high temperature dissolution and remolding. Plastic production equipment needs to continuously add production materials to the equipment during production until the product is completed and the equipment is cooled. From this point of view, as long as the color of the material is changed without stopping, it is equivalent to changing the color of the product while producing, which is theoretically possible.

However, plastic production equipment needs to be processed by molds during production, and mold debugging is particularly important. If you randomly change the ratio of materials or the properties of the materials during production, it is extremely easy to cause damage to the mold. Once the mold is damaged, the cost loss is huge.

In daily work, if the color of the same product needs to be changed, the next color will be produced after the machine is cleaned and maintained after one color is produced. The machine must be adjusted to color before production, and mass production will only be carried out when all the values are normal. So although it is achievable in terms of ideas, but in terms of production process and production rigor, try not to do this as much as possible.
