近年來，金屬製品製造業和非金屬礦物製品製造業一直是全球製造業中的重要部門。其中，鎂鋁合金和鎂合金是常見的金屬材料，而塑膠外殼及配件則是非金屬製品的代表。
在製造過程中，表面處理是至關重要的一環。通過表面處理，可以提高金屬和非金屬製品的耐腐蝕性和耐磨性，延長其使用壽命。前處理則是表面處理的重要步驟，能夠確保表面處理的效果更加持久。
隨著環保意識的提高，非鉻酸等環保表面處理技術逐漸取代傳統的鉻酸表面處理技術。粉體塗裝和液體塗裝也成為金屬製品製造中常見的表面處理方法，能夠提供更好的外觀和保護效果。
未來，金屬製品製造和非金屬礦物製品製造將朝著更加智能化和自動化的方向發展。噴漆技術的進步和應用將使製造過程更加高效和環保。同時，金屬與非金屬製品製造業將更加注重產品的品質和創新，以滿足消費者不斷變化的需求。

Title: Future Development Trends in Metal and Non-metal Products Manufacturing Industry
Article: In recent years, the metal products manufacturing industry and non-metal mineral products manufacturing industry have been important sectors in the global manufacturing industry. Magnesium-aluminum alloy and magnesium alloy are common metal materials, while plastic casings and accessories represent non-metal products.
Surface treatment is crucial in the manufacturing process. Through surface treatment, the corrosion resistance and wear resistance of metal and non-metal products can be improved, extending their service life. Pretreatment is an important step in surface treatment to ensure the lasting effect.
With the increasing environmental awareness, environmentally friendly surface treatment technologies such as non-chromium acid are gradually replacing traditional chromium acid surface treatment technologies. Powder coating and liquid coating have also become common surface treatment methods in metal products manufacturing, providing better appearance and protection.
In the future, metal products manufacturing and non-metal mineral products manufacturing will move towards a more intelligent and automated direction. The advancement and application of spray painting technology will make the manufacturing process more efficient and environmentally friendly. At the same time, the metal and non-metal products manufacturing industry will focus more on product quality and innovation to meet the ever-changing consumer demands.
