FAQ

Q

When a six-axis industrial robot is linked with a die-casting machine and peripheral equipment, signal delays occur, disrupting the production rhythm. How should we troubleshoot this issue?

A
Prioritize troubleshooting in two areas: First, check the communication lines between devices to ensure that communication interfaces such as Ethernet and Profinet are securely connected, and that communication cables are undamaged. Reconnect the interfaces or replace the cables if necessary. Second, examine the control system’s program to verify that the signal interaction logic between the robot and the die-casting machine is correct and that no program conflicts exist. If needed, re-optimize the timing sequence for triggering the coordinated program.
Q

What risks arise if the hydraulic oil temperature exceeds 60℃ during die casting machine operation? How can the temperature be reduced?

A
There are two risks: First, the viscosity of the hydraulic oil decreases, leading to unstable pressure in the hydraulic system and affecting die-casting accuracy. Second, hydraulic components (such as seals and valve spools) age more rapidly, increasing the likelihood of failures. Cooling methods: Check whether the hydraulic oil radiator is blocked, and clean dust and oil deposits from its surface. If the cooling effect is insufficient, you can install an additional cooling fan or a water-cooled cooler to forcibly reduce the hydraulic oil temperature.
Q

What can be done to reduce excessive slag formation in the molten alloy inside an industrial furnace?

A
Three measures can be taken: First, select raw materials with higher purity (such as aluminum alloy ingots with low impurity content) to minimize the introduction of impurities. Second, during the alloy melting process, add slag-removing agents (such as refining agents) in proportion to adsorb impurities from the molten metal and allow them to float to the surface; regularly remove the floating slag. Third, control the heating rate of the furnace to prevent localized overheating, which could exacerbate alloy oxidation. Typically, the heating rate for aluminum alloy melting should not exceed 10°C/min.
Q

What should be done if workpiece transport gets stuck on automated peripheral production lines for die casting (such as automatic edge trimming and deburring lines)?

A
First, perform a two-step troubleshooting procedure: 1. Conduct a preliminary inspection to check whether there are any foreign objects (such as metal scraps or casting burrs) on the conveyor track. Clean the track and lubricate the track rollers. 2. In the second step, adjust the speed and tension of the conveying mechanism. If the conveyor uses a belt, check the belt’s tightness and adjust the tension pulley accordingly. If the conveyor uses a chain, lubricate the chain and tighten any loose chain links.
Q

When using a six-axis industrial robot in a die-casting workshop, how can we prevent it from being damaged by splashes of molten metal?

A
Three protective measures must be taken: First, install splash guards on the robot and select materials that are resistant to high temperatures and corrosion (such as stainless steel plates or high-temperature-resistant rubber). Second, wrap high-temperature-resistant protective sleeves around the robot’s critical components (such as joints and cables) to prevent direct contact with molten metal. Third, when setting the robot’s motion paths, avoid areas where molten metal may splash and maintain a safe distance (typically no less than 500 mm).
Q

What impacts does an excessively high mold temperature in a die-casting machine have on production, and how can it be controlled?

A
The main impacts are threefold: First, castings are prone to defects such as shrinkage cavities and cracks, which reduce the product’s qualification rate. Second, the mold’s service life is shortened—high temperatures accelerate mold wear and deformation. Third, demolding becomes difficult, potentially leading to casting sticking to the mold. The control measures include: activating the mold cooling system (such as cooling water channels or spray cooling) and ensuring stable flow and temperature of the cooling water; and appropriately adjusting the production cycle to prevent the mold from being continuously exposed to high temperatures for extended periods.
