About Dongguan Shengwei Plastic Products Co., Ltd - Injection Moulded Products Supplier in China

Dongguan, China hosts Dongguan Shengwei Plastic Products Co., Ltd, which lists 59 active products across a wide spectrum of injection‑moulded items. The catalogue covers plastic gear motor moulds, home‑appliance lamp covers, washing‑machine parts moulds, remote‑control cases, pet bowls, sports kettle covers and a variety of automotive components such as door‑board injection parts, air‑bag covers and tube‑valve parts. Three entries carry explicit HS classifications: HS 8480.41 for auto rubber compression plastic mould parts, HS 8480.71 for general auto parts, and HS 8708.99 for auto tube valve parts, reflecting their placement in machinery and vehicle‑parts chapters. The product set also includes consumer‑oriented items like baby products, lunch boxes and toy shells, illustrating a blend of industrial and household applications.

In addition to the listed items, the supplier offers custom plastic moulds for automotive, appliance and equipment sectors. Materials noted in the catalogue include pre‑hardened tool steel (H13, NAK80, P20) for moulds and engineering plastics such as PP, PA, POM and ABS for the finished parts. The presence of both material and HS‑code details demonstrates capability to serve sectors that require precise grade specifications and compliance with machinery‑parts tariff codes.

Product Range and Specialties of Dongguan Shengwei Plastic Products Co., Ltd

The catalogue enumerates items ranging from LED‑light lens covers and computer plastic cases to specialised automotive moulds and motorcycle helmet moulds. Typical industry practice for these categories involves using polypropylene (PP) grades with melt flow indices between 8‑12 g/10 min, ABS grades meeting ASTM D638 tensile standards, and POM grades for low‑friction applications. Automotive moulds are frequently produced from H13 or P20 tool steel to achieve hardness of 45‑55 HRC and thermal stability up to 540 °C, matching ISO 9001 quality‑management expectations. For consumer‑grade plastic parts, manufacturers often target ISO‑9001 certification and comply with REACH and RoHS limits on heavy metals, with colour matching performed to RAL or Pantone standards where required.

The supplier’s custom mould services enable production of low‑volume runs (as few as 500 pcs) and high‑volume batches exceeding 20 000 pcs per month. Standard packaging for bulk plastic components includes shrink‑wrapped pallets, while delicate items such as LED lenses are boxed individually with foam inserts to meet ASTM D4169 shipping test criteria.

Trade and Export Information - Dongguan Shengwei Plastic Products Co., Ltd

China remains one of the world’s largest exporters of injection‑moulded plastic components, with the HS 8480 family covering machinery parts and HS 8708 covering vehicle parts. Major import destinations for Chinese plastic moulded goods include the European Union (Germany, Italy, France), North America (USA, Canada) and Southeast Asian markets (Vietnam, Thailand). Buyers typically request ISO 9001 quality‑management certification, CE marking for safety‑related automotive parts, and RoHS/REACH compliance documentation. Export shipments are commonly arranged on 40‑ft containers using FOB or CIF Incoterms, with pallets stacked to a maximum height of 2.2 m and secured with stretch film to satisfy container loading standards.

Regulatory inspections frequently involve pre‑shipment sampling under the EU CPNP system for plastic articles, while US imports may be subject to FDA or CPSC testing depending on end‑use. Chinese manufacturers often provide a Material Safety Data Sheet (MSDS) and a test report according to ASTM or ISO standards to facilitate customs clearance and buyer verification.

Sourcing from Dongguan Shengwei Plastic Products Co., Ltd - Buyer Guidance

When sourcing from this supplier, buyers should request a detailed material data sheet specifying polymer grade, melt flow index, tensile strength and impact resistance (e.g., ASTM D638, ISO 179). For moulded automotive parts, ask for tool‑steel grade certificates and proof of compliance with ISO 9001 or IATF 16949 if the end‑customer requires automotive‑specific quality systems. Verify that the HS code declared matches the product description to avoid tariff misclassification.

Confirm packaging details: bulk parts are typically palletised on Euro‑pallets, wrapped in stretch film, while small consumer items are boxed with protective inserts. Request a pre‑production sample and a third‑party inspection report (e.g., SGS, Intertek) before approving full‑scale production. Clarify lead times - standard catalogue items may ship within 15‑30 days, whereas custom moulds generally require 45‑70 days depending on tool‑making complexity.

What plastic materials are commonly used for the supplier's injection‑moulded parts?

The catalogue references engineering plastics such as polypropylene (PP), polyamide (PA), polyoxymethylene (POM) and acrylonitrile‑butadiene‑styrene (ABS). These grades are typical for consumer and automotive applications and meet ASTM D638 tensile standards.

Are the automotive moulds compliant with any specific quality standards?

The supplier lists tool‑steel moulds made from H13, NAK80, P20 and similar grades, which are compatible with ISO 9001‑based quality‑management systems commonly required for automotive component manufacturers.

Which HS codes apply to the supplier's automotive components?

Two explicit HS codes appear in the catalogue: HS 8480.41 for auto rubber compression plastic mould parts, HS 8480.71 for general auto parts, and HS 8708.99 for auto tube valve parts. These fall under the machinery‑parts and vehicle‑parts chapters.

What is the typical minimum order quantity for custom plastic moulds?

Custom mould orders generally start at 500 pieces for low‑volume production, with larger runs scaling to 20 000 pieces or more depending on the part geometry and tooling cost.

How are finished parts packaged for overseas shipment?

Bulk components are usually palletised on Euro‑pallets, shrink‑wrapped, and loaded into 40‑ft containers. Small or delicate items such as LED lenses are individually boxed with foam inserts to meet ASTM D4169 shipping test requirements.

Which certifications should a buyer request when purchasing these goods?

Buyers should request ISO 9001 quality‑management certificates, CE marking or IATF 16949 for automotive parts, and RoHS/REACH compliance statements for consumer plastic items. Third‑party test reports (e.g., SGS, Intertek) provide additional assurance.

What lead time can be expected for standard versus custom products?

Standard catalogue items typically ship within 15‑30 days after order confirmation. Custom moulded parts require tool‑making and trial runs, resulting in a lead time of roughly 45‑70 days.

Can the supplier produce parts in specific colors or surface finishes?

Yes, the supplier can colour‑match to RAL or Pantone specifications and apply surface treatments such as matte, gloss or textured finishes, depending on the chosen polymer grade and mould design.
