Skeleton supplier tells you the production process of transformer skeleton products

The skeleton supplier tells you that the injection molding process is to inject the molten bakelite raw material and plastic original object at high temperature into the cavity of the skeleton mold through the pressure of the injection molding machine. After a certain molding and cooling time, the skeleton is separated from the mold through the injection system. The process control focuses on the temperature and pressure during injection, as well as the proportion of the raw material recovered inside the plastic raw material. The reform of injection temperature and pressure must influence the reform of the basic dimensions of the raw material, the reform of the strength and properties of the raw material, and the reform of the thickness of the rough edge. The thickness of the rough edge will also directly affect the operation of the next process. Within this process, IPQC can introduce SPC to monitor this series of changes, so that changes can be detected and adjusted as soon as possible to better ensure the quality of the raw material. Finished molds need to be cleaned and maintained in a timely manner to extend the life of the molds and bring more benefits to the company.

In addition, in today's increasingly strict environmental requirements, the control of plastic original raw objects (including recycled raw objects, green raw objects and non-green raw objects) is more important. Skeleton suppliers tell you how to avoid the pollution of non-green original objects to green original objects, will be the focus of subsequent processing enterprises.

1. Companies do not buy or produce non-green raw materials, which is certainly more effective.

2. Detailed records of the state of incoming materials within the molding process, including the type, batch number, time and quantity of the above-mentioned original objects.

3. Strict management of recycled original objects, try to keep the model and lot number consistent with the original bag.

4. Distinguish the shredder and mixer according to the series or model of the original original object (such as PA, PBT, PET, etc.) to avoid mutual contamination due to cleaning the machine.

5. Reduce or do not use external release agents and lubricants that have not passed the green test.

6. Try to use natural color raw materials for production and avoid using color masterbatches.

The skeleton supplier tells you that the process is mainly for bakelite skeleton. In order to smoothly discharge the gas generated inside the molding process, we need to add exhaust grooves to the mold. The molten raw material fills the venting groove under high pressure, so we need to use a rough edge processor to process the rough edge by a specific process. Within the rough edge control, we need to measure the raw material size to determine if the skeleton size is affected by the rough edge thickness; in addition, we generally determine if the rough edge can be cleaned by light transmission.

Within the rough edge treatment process, we should choose the size of the sand according to the structural characteristics of the raw material, such as the size of the wire groove and the strength of the raw material blade. Otherwise, the sand will be stuck inside the wire groove and block the copper wire, or it will be stuck inside the pin hole and affect the next pin insertion process. After inserting the pin, try not to rough edge processing, otherwise it will affect the verticality of the pin.

For plastic products, manual processing is the way to go. SMD type Bakelite raw material can be processed by tunnel rough edge machine first, and then manually remove the rough edge attached to the terminal.
