About Longmold Technology Co., Ltd. - Injection Moulded Products Supplier in China

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.

Product Range and Specialties of Longmold Technology Co., Ltd.

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.

Trade and Export Information - Longmold Technology Co., Ltd.

Chinese mold manufacturers like Longmold Technology Co., Ltd. export tooling primarily to automotive, consumer‑goods, and electronics producers in Europe, North America, and Southeast Asia. The typical HS chapters for these products are 84 (machinery) and 85 (electrical equipment), and customs authorities often request a commercial invoice, packing list, and certificate of origin. Buyers frequently require ISO 9001 quality‑management certification, CE marking for EU markets, and, where applicable, UL or CSA approval for North American applications. Standard export packaging includes wooden crates with internal cushioning, sized to fit 20‑ft or 40‑ft containers, and moisture‑resistant barriers are used for steel tooling to prevent corrosion. Freight terms such as FOB Shanghai or CIF destination port are common, with lead times ranging from 30 to 90 days depending on mold complexity and material certification.

Sourcing from Longmold Technology Co., Ltd. - Buyer Guidance

Prospective buyers should request detailed engineering drawings and a bill of materials before confirming an order, as these documents reveal the proposed steel grade, heat‑treatment cycle, and cavity dimensions. Sample molds or prototype runs are useful to verify dimensional accuracy, surface finish, and cooling performance, and test reports such as hardness (Rockwell) and tensile strength should be supplied. It is advisable to obtain the supplier’s ISO 9001 certificate and, where required, CE or UL compliance documents, and to verify that the export packaging meets the buyer’s logistics specifications. Clarifying the minimum order quantity, expected lead time, and the preferred Incoterm early in the negotiation helps prevent delays, especially for complex hot‑runner or gas‑assisted systems.

What types of molds does Longmold Technology Co., Ltd. offer?

The supplier lists six mold types: blow mould, plastic injection mould, gas‑assisted mould, die‑casting mould, precise mould and hot‑runner mould. Each corresponds to a distinct manufacturing process within plastic or metal forming.

Which certifications should a buyer request from this supplier?

Buyers should ask for the supplier’s ISO 9001 quality‑management certificate, and, if the molds are destined for the EU, a CE conformity declaration. For North American markets, UL or CSA approval may also be required.

What technical documents are typically needed before placing an order?

Standard documentation includes CAD drawings, a bill of materials, material‑grade certificates, heat‑treatment reports, and dimensional inspection reports such as CMM data. Hardness test results (Rockwell) are also common for steel tooling.

What are the usual lead times for the listed mold types?

Lead times depend on complexity; simple blow or injection molds may require 30‑45 days, while gas‑assisted, precise or hot‑runner systems often need 60‑90 days to complete tooling and testing.

Is there a minimum order quantity for molds from this supplier?

Most Chinese mold makers set a minimum order of one complete mold, but the buyer should confirm any tooling‑specific MOQ, especially for large die‑casting molds that may involve higher material volumes.

How are the molds packaged for international shipment?

Molds are typically crated in reinforced wooden boxes with internal foam or wooden pallets, and the crates are sized to fit standard 20‑ft or 40‑ft containers. Moisture‑resistant liners are added to protect steel surfaces during sea freight.

Which Incoterms are commonly used for shipments from Longmold Technology Co., Ltd.?

Exporters in China frequently use FOB Shanghai or CIF destination port, allowing the buyer to choose between arranging their own freight forwarder or receiving a cost‑included shipment.
