Nanhaiya typically uses high-strength alloy steel, such as 38CrMoALA, which possesses excellent mechanical properties and wear resistance, providing good basic strength and toughness for the barrel. The barrel lining adopts a bimetallic composite structure, with the inner lining layer mostly made of high-chromium cast iron, nickel-based alloys, or tungsten carbide sprayed materials.

Single screws can be used for:

PE water supply pipes, PVC drainage pipes, PPR hot water pipes, gas pipes; PVC decorative sheets, PP food-grade sheets (for blister packaging), PS foam sheets; PE cling film, LDPE agricultural film, PP packaging film; PVC door and window frames, plastic skirting boards, automotive sealing strips (soft PVC or TPE material); general-purpose PE granules, PVC profile-specific granules, masterbatch (high-concentration pigment granules); recycled PE granules (for producing garbage bags), recycled PP granules (for producing plastic pallets).
