Sunci extrusion machines have key advantages over other suppliers' machines due to their use of high-quality raw materials. Sunci uses stainless steel for their high temperature sulfur oven and hot air horizontal oven, which makes them more durable and prevents rusting. Other suppliers may use painted steel, which can rust over time and release harmful gases. Sunci's ovens also maintain a high inner temperature of 600°C while keeping the outer temperature low between 40-60°C, solving a key engineering challenge. These high-quality ovens allow Sunci machines to safely produce food and medical silicone products.
