From the part, we can easily find that the parts have a lot of features of big cavities, so the part will have big potential risk of mold release problem, if so, the part may happen to be deform, sticking to the mold etc, especially when the part sticking to the mold, if no clear in time, while next shot, the mold may be destroyed while clamping.

Fish cage cultivation techniques for autumn and winter
Fish farming in cages during autumn and winter offers several advantages, especially when fish are moved into the cages after being fattened in ponds. By this time, the fish have stronger constitutions and adapt more easily to the cage environment. Additionally, overwintering in large water bodies allows for better survival rates compared to pond-farmed fish. Fish that are overwintered in cages experience less weight loss and start feeding earlier in spring, extending their growth period by about a month compared to those introduced in spring. This leads to faster growth and significantly higher yields. In fact, fish overwintered in cages grow approximately 30% faster and reach marketable sizes about 35% sooner than those introduced in spring. Therefore, it is a scientifically sound practice to stock fish in cages during the winter.
To ensure successful stocking, the water temperature should be between 15°C and 18°C when transferring fish into the cages. If the water temperature drops below 10°C, the process should be avoided. Before placing the fingerlings into the cages, disinfection should be done during transportation. About 20 to 30 minutes before arriving at the destination, a disinfectant such as methylene blue should be added to the transport container. The dosage must be accurately calculated and not estimated arbitrarily.
Seven to ten days before stocking, the cages should be placed in the water to allow algae or sediment to form on the net surfaces. This helps prevent injury from new nets scratching the fish. After being stocked, the fish should be fed medicated feed for a short period to help heal any injuries sustained during handling and transport, reducing the risk of disease.
Before winter, feeding should be gradually reduced as the water temperature drops to around 5°C to 6°C. At this point, fish stop eating naturally, and maintaining their health is crucial to avoid weakness caused by early starvation. When the water temperature reaches about 4°C, the water column becomes stable, with minimal convection between upper and lower layers. This stability helps the fish remain physiologically calm, avoiding stress caused by water layer changes.
