Abog | AI tuning - improving the stability of material return production

With the increasing demand for cost reduction and environmental protection, the use of crushed materials is also growing. However, during the use of crushed materials, there may be issues such as unstable storage and differences in material flowability, which can affect the stability of the product. In this article, we will discuss fromHardware adaptation/software regulation/SensorimproveLet's talk about how to improve the stability of material recycling production from three aspects.

　　① Hardware adaptation:

Unstable feeding of crushed materials? The problem lies in the 'entrance'.

Returning materials is not as "regular" as new materials - large particles are prone to getting stuck at the hopper mouth and cannot fall into the screw; Fine dust is too "urgent" and melts in advance before sticking to the screw. Over time, it will carbonize and the product will appear mottled and black spots.

Abog's solution is very straightforward:

Large particles? Using a high compression ratio screw, the screw groove is deeper and can be swallowed with a big mouth.

Fine dust? Using coated screws to reduce the adhesion between plastic and metal, achieving "non stick and non carbonized" properties.

② Software control:

Abog machines can be optionally selectedRecycled PilotFunction As mentioned above, there is instability in the storage process of crushed materials. If the pressure is switched according to the conventional screw position, there will be differences in the volume of material injected into the mold cavity at the turning point, which may lead to differences in product quality. The material return navigation function will analyze the difference between the current pressure curve and the reference curve to identify the differences in the closure of the check ring and material viscosity, and improve the stability of the injection volume by automatically adjusting the transfer pressure point.

In injection molding, injection pressure is divided into three types: system pressure, screw pressure, and mold cavity pressure. The most direct impact on product quality isMold cavity pressureMore and more customers are choosing precisionmoldAdd mold cavity insidePressure sensorAnd the Abog machine can optionally integrate the mold cavity pressure sensor into the injection molding machine controller. ThroughReference PilotFunction: The holding pressure can be switched by the mold cavity pressure, and after entering the holding pressure, the machine can adjust the holding speed and pressure by itself to achieve the coincidence of each mold cavity pressure curve with the reference curve, thereby achieving consistency in product quality.
