Import 718h Plastic Mould — Buy in Bulk from Supplier in China

718H plastic mould steel from Foshan Baote Special Steel Co., Ltd. is a pre-hardened CrMo alloy steel delivered in hot-rolled or hot-forged condition at HRC 30 to 35, ready for direct machining without additional heat treatment. The material is produced via electric furnace (EF), ladle refining (LF), and vacuum degassing (VD) to ensure high purity. Available dimensions span thickness 65 to 610 mm, width 610 to 1500 mm, and length 2000 to 6000 mm, giving buyers substantial flexibility for mould bases, cavities, and cores.

The steel's chemistry centres on chromium and molybdenum additions that provide uniform hardness through section, good polishability, and consistent response to texturing and etching. Vacuum refining reduces inclusions, which is critical for achieving mirror finishes on refrigerator and air-conditioning panels. Nitrogen surface treatment can raise hardness to HV 680, extending die life to approximately 100 million cycles under typical injection moulding conditions. Standard industry practice for 718H grade (AISI P20+Ni equivalent) expects sulphur below 0.015% and phosphorus below 0.025% to protect polish quality.

This grade suits manufacturers of high-gloss appliance moulds, automotive interior trim, and consumer electronics housings where EDM processing and photo-etching are routine. Buyers typically confirm whether the supplier provides ultrasonic testing certificates, mill test reports with actual chemical composition, and pre-hardened flatness tolerances. Incoterms and exact delivery schedules should be discussed directly with Foshan Baote Special Steel Co., Ltd., as these are not stated in the listing.

Foshan Baote Special Steel Co., Ltd. operates from No.13-2 Xihai Industrial Zone in Lecong Town, Shunde District, Foshan City, Guangdong Province, postal code 528315. The company holds a Harbor trust tier on the platform, with no response-rate or average-response-time data currently recorded. This absence of engagement metrics means buyers should expect to initiate contact and confirm responsiveness directly.

The listing presents Foshan Baote as a specialist in pre-hardened plastic mould steels with vacuum-refined CrMo grades, emphasising polishability, etching performance, and nitriding suitability. No information is provided about year of establishment, production capacity, export volume, ISO certification, or named clients. Buyers should request a current mill certificate, proof of vacuum-degassing capability, and references from appliance-mould end users before committing to volume orders.
