銅缸鑄造是一項傳統技藝，其制作過程需要嚴格控制每個環節的質量和細節，那我們應該如何在銅缸鑄造過程中避免劃傷和沾灰呢！
Copper cylinder casting is a traditional craft, and its production process requires strict control of the quality and details of each link. So how should we avoid scratches and dust during the casting process!
1. 鑄造時必須嚴格控制溫度，過高的溫度會導致銅缸變形或產生氣孔；溫度過低則會造成縮松現象。
1. During casting, temperature must be strictly controlled. Excessive temperature can cause deformation of the copper cylinder or the formation of pores; If the temperature is too low, it will cause shrinkage and looseness.
2. 澆注時必須保證銅液均勻注入模型中，防止出現未充滿的現象。
2. During pouring, it is necessary to ensure that the copper liquid is evenly injected into the model to prevent underfilling.
3. 修整和拋光時要保持銅缸表面的平整度和光澤度。
3. When repairing and polishing, it is necessary to maintain the flatness and glossiness of the surface of the copper cylinder.
4. 包裝前必須確保銅缸表面干凈整潔，避免沾染灰塵或劃傷表面。
4. Before packaging, it is necessary to ensure that the surface of the copper cylinder is clean and tidy, avoiding dust or scratches on the surface.
5. 在整個制作過程中，要注意安全，防止高溫和尖銳的工具傷害自己或他人。
During the entire production process, attention should be paid to safety to prevent high temperatures and sharp tools from harming oneself or others.
