In many industrial furnaces with complex inner cavity structure, standard blanket, board and module cannot satisfy installation requirement. Custom‑made AES bio‑soluble fiber special‑shaped parts, including cones, sleeves, square blocks, irregular transition pieces, are widely adopted. Many customers wonder why these custom‑shaped products have relatively high unit price.

First of all, custom special‑shaped AES components often need dedicated mould development. Opening‑mould cost will be allocated to batch products. Different drawing dimensions correspond to different moulds, which brings extra manufacturing expense. Secondly, most custom parts belong to small‑batch production. Continuous mass production cannot be realized like standard blanket or board, resulting in lower production efficiency.

Precision cutting and finishing process also consume extra labor. For complex curved surfaces and hole positions, workers need manual trimming and inspection one‑by‑one to guarantee dimensional tolerance. AES soluble fiber raw material itself costs higher than ordinary RCF raw material, which further pushes up finished‑goods price.

Even though custom‑shaped parts have higher cost, they bring great engineering value. Pre‑fabricated special‑shaped pieces reduce on‑site cutting workload, lower dust generation on construction site, and ensure fitting accuracy for complex furnace structure. For key equipment with non‑standard inner cavity, custom AES shaped components are irreplaceable solution.
