Longmold Technology Co., Ltd.

Longmold Technology Co., Ltd. is based in China and currently lists six active products in its catalogue. The supplier focuses on injection moulded products and plastic processing machinery, as indicated by its top categories. Its product portfolio includes blow molds, plastic injection molds, gas‑assisted molds, die‑casting molds, precise molds and hot‑runner molds. These items are presented without accompanying HS codes in the supplied data. The active product count of six aligns with the six distinct mold types enumerated. The catalogue does not disclose additional accessories or auxiliary equipment.

Each listed mold type serves a specific manufacturing process within the broader plastic and metal forming industries. Blow molds are used for extrusion blow‑forming of hollow parts, while plastic injection molds shape molten polymer under high pressure. Gas‑assisted molds introduce nitrogen to reduce material usage and improve surface finish, and die‑casting molds are employed for high‑pressure metal casting. Precise molds target tight dimensional tolerances for medical or electronic components, and hot‑runner molds incorporate heated runner systems to reduce waste. Although the facts omit HS‑code numbers, such tooling is generally classified under the machinery and equipment chapters of the customs tariff. The supplier’s catalogue does not specify material grades or surface‑finish specifications, leaving those details to be confirmed during the sourcing process.

The catalogue’s six mold types cover the main segments of tooling required for high‑volume plastic and metal part production. In the injection moulding sector, standard molds are commonly fabricated from P20 or H13 tool steel with a hardness of 30‑35 HRC and a surface roughness of Ra 0.8 µm. Blow moulds for PET bottles often use aluminum or steel cores with a cavity tolerance of ±0.05 mm, while gas‑assisted molds add nitrogen channels to achieve similar tolerances with reduced material. Die‑casting molds typically employ high‑strength steel such as H11 and are designed for cycle times under 30 seconds. Precise molds for medical devices may require stainless‑steel grades (e.g., 304) and tighter tolerances of ±0.01 mm, and hot‑runner systems are built with temperature‑controlled manifolds to maintain melt temperature within ±2 °C. Buyers generally expect documentation of material grade, heat‑treatment reports, and dimensional inspection certificates for each mold type.
