大龍以最基本的手積層起家，後續從歐洲導入最新製程，並納入自行研發的獨特工法來協助降低成本，我們製造經驗及多元化的製程可配合客戶需求因應不同的產品需求。


1.Hand Lay-up/手積層 

Hand lay-up is the most traditional method for the manufacture of fiber-enforced.The process is simple. Fiber mat is first laid in the mould and is then saturated with fluid resin. The laminate is then compressed to ensure optimal bonding between mat and resin and to remove air from between the resin and the fiber.
Advantage: Low investment costs, applicable to a small amount of diversity production and the large item production.  

手積層是最傳統的複合材料成品製程，此工法幾乎可以應用於任何產品的生產製作，而且成本最低。
優點: 投資成本低，適用於少量多樣性與大型物件的生產 

 

 

2.Vacuum Molding/真空 

This process is a vacuum-assisted, resin transfer process with a flexible solid counter tool for the one-side surface compression. It is one of major interest for various molding applications as it promises performance improvements and cost savings over traditional methods.
Advantage: Excellent weather resistance, good adhesion and consistent product thickness and weight.

真空相較於手積層擁有較高的強度與剛性，而且重量輕，耐衝擊能力高，我司採用特殊製作方法，內層也可看到平整的紋路。
優點:耐候性與密合度佳、產品厚度與重量穩定性佳
 

 

3.Blow Molding/吹塑

It basically consists of taking fiber and resin substrate; used to inflate soft plastic into a mold cavity. Over a long-term period of research, this process has become one of our unique technical characteristics. 
Advantage: Excellent weather resistance, lightweight products which is both strong and rigidity, this method is suited for complex main body, pipe and complex tube 

異形管的製作即是採用此種製程，與真空製程有相同優點，適用於管件的部分。
優點:耐候性佳、產品輕量化兼具強度與剛性，用於複雜性的主體、管件與異形管

 

 

 

 

4.Thermoforming熱壓 / 熱塑

Thermoforming is that use carbon fiber prepreg / carbon sheet heating to a pliable and to pressurize it forming it on the mold.
Advantage: Can be mass produce, excellent product size consistency, not easy to deform and is weather resistence, strong and rigid.

此兩種製程不同之處在於材料不同，熱壓材料為預浸碳纖維布 (Carbon fiber prepreg)，熱塑材料為碳纖板材，皆適用於對尺寸要求精準的產品。
優點: 兩者皆可大量生產，產品尺寸穩定度高、不易變形兼具耐候性、強度、剛性。
熱塑具環保特性可重複利用與循環再造，但不適用複雜的主體
