Import Blowing Moulds — Buy in Bulk from Supplier in China

Blowing moulds from Spring Plastic & Mould Industry Co., Ltd. are precision-engineered tooling components for extrusion and stretch blow moulding of polyethylene terephthalate (PET), high-density polyethylene (HDPE), and polypropylene (PP) containers. The moulds are fabricated from aluminium alloy 7075-T6 or stainless steel 2Cr13, with cavity counts ranging from single to eight-cavity configurations depending on bottle geometry and output requirements. Surface finishing includes diamond-turned or hand-polished cavities to Ra 0.025 micron, ensuring optical clarity and minimal parison marking on finished bottles.

The construction methodology varies by application: aluminium moulds offer rapid heat transfer and lighter weight for complex neck geometries, while steel moulds provide extended service life beyond five million cycles in high-volume carbonated soft drink lines. Typical cavity wall thickness ranges from 25 mm to 40 mm, with cooling channel spacing at 15-20 mm pitch for uniform thermal management. Venting is addressed through parting-line vents (0.02-0.05 mm depth) and cavity insert vents to prevent air traps in deep shoulder or undercut designs. Standard neck finishes include PCO 1881, 28 mm pco, and 38 mm push-up configurations for beverage applications.

Primary buyers include converters serving the bottled water, carbonated drinks, edible oils, cosmetics, and pharmaceutical sectors, where container dimensional tolerance (+/- 0.3 mm on body diameter) and weight consistency are critical. The supplier's location in Huangyan, Taizhou, Zhejiang Province places it within China's densest cluster of mould fabrication capacity, with access to specialized high-speed CNC and five-axis machining centres. Trade terms require direct confirmation with Spring Plastic & Mould Industry Co., Ltd.; prospective buyers should request cavity steel certification, sample bottle testing protocols, and blow moulding machine compatibility sheets before order commitment.

Spring Plastic & Mould Industry Co., Ltd. operates from No 255-263 Yinshan Road in Huangyan District, Taizhou, Zhejiang Province, China (postal code 318020). The Huangyan moulding cluster, often termed China's mould town, hosts several thousand tooling enterprises with concentrated expertise in plastic injection and blow mould fabrication. The supplier holds a harbor trust tier on the platform, with a response rate of 0.00 percent and no recorded average response time, indicating that direct enquiry may be necessary to establish communication reliability and technical support availability.

The supplier's profile does not disclose annual revenue, employee count, specific client references, or ISO/CE certification documentation; buyers should verify quality management system credentials and request mould trial reports directly. The address suggests a mid-scale operation rather than a large corporate entity, which may offer pricing flexibility but requires more rigorous incoming quality inspection protocols. Prospective importers should confirm whether Spring Plastic & Mould Industry Co., Ltd. provides in-house mould trial capability, spare cavity insert inventory, and after-sales adjustment services, as these factors significantly impact total cost of ownership for blow mould tooling.
