鑄鋁加熱器（闆式）經精加工後它能和被加熱體緊密貼合。其使用溫度一般在攝氏150～450度之間，可廣泛應用於塑料機械、模頭、電纜機械、化工、橡膠、石油等設備上。是以管狀電熱元件為發熱體，並彎麯成型，用優質鑄材料為外殼，外殼以離心式澆鑄成各種形狀的電加熱器，有圓型、平闆、直角型、風冷、水冷及其它異型等。
鑄鋁加熱器（闆式）技術特性
1.鑄鋁加熱器（闆式）錶麵負荷可達到2.5-4.5w/cm²，工作溫度300-450℃之間；
2.鑄鋁加熱器（闆式）是一種熱分部均勻的加熱器，熱導性好的金屬合金，確保熱麵溫度均勻，消除了設備的熱點及冷點。具有長壽命、保溫性能好、機械性能強、耐腐蝕、抗磁場等優點。將外散熱麵增加保溫裝置，內散熱麵燒結紅外線這樣可節約用電35%。
應用範圍
鑄鋁加熱器（闆式）鑄鋁加熱器（闆式）主要用於塑料工業註塑機、擠出機和吹塑機的加熱，同時也可用於反應釜、熔體管道等化工領域的加熱。
産品結構
採用電加熱管，澆鑄在鋁或銅等金屬材料中，加熱絲與空氣隔絕，加熱體堅固耐用，加熱均勻，熱交換迅速，可在加熱體內設置冷卻水道或風道。特殊環境中採用防爆接線盒，如需保溫，則配置保溫層。
技術參數
鑄鋁工作溫度可達350℃，功率密度可高至3.5W/cm²。
鑄銅工作溫度可達650℃，功率密度可高至8W/cm²。
Application
It is mainly applied to heating the plastic injection molding machine, extrusion machine and blowing machine. Meantime, it also can be used to heat reaction kettle, melt pipe, etc in chemical industry.
Structure
The electric heating tube is adopted with its heating strip casted inside the metal material such as aluminum or copper and isolated from the air. The heating body is tough and durable, which heats evenly and exchanges heat very fast. Cooling water or air duct could be set up inside the heating body for option. In particular environment, we use anti-explosion junction box. If thermal preservation is needed, we shall add insulation layer.
Technical parameter
The working temperature and the power density of cast aluminum are respectively up to 350℃℃ and 3.5W/cm2.
These of cast copper are 650℃℃ and 8W/cm2.
