Ningbo Shaoxuan Mould Technology Co., Ltd. is located at No.3 Shaodong Road, Fengshan Sub‑district, Yuyao, Ningbo, within the core industrial belt of Yuyao China Light Industry Mould City. It is an integrated manufacturer specializing in the R&D and production of plastic moulds.
The founder has 18‑year in‑depth experience in the plastic pipe fitting mould industry, and the team boasts 10‑year experience in processing and R&D. The company focuses on custom‑built moulds for pipe fittings, irrigation systems, plastic pipe fittings, PVC pipe fittings, PVC ball valves and PPR pipe fittings.
Equipped with a full set of processing and testing equipment including CNC milling machines, EDM machines, wire‑cut machines and engraving machines, the factory completes the whole‑process in‑house processing for pipe fitting moulds with minimal outsourced work, so as to reliably control the precision and delivery schedule of PPR and PVC pipe fitting moulds. Benefiting from Yuyao’s complete mould industrial cluster with well‑supported steel materials and heat‑treatment services, the delivery lead‑time for various plastic pipe fitting moulds can be effectively shortened. Situated close to expressways and railways, and 70 kilometres away from Ningbo Lishe International Airport, the plant enjoys convenient sea, land and air logistics, catering to both domestic distribution and export shipments.
The company mainly engages in moulds for plumbing pipes, with core offerings of pipe fitting moulds, irrigation moulds, plastic pipe fitting moulds, PVC pipe fitting moulds, PVC ball valve moulds and PPR pipe fitting moulds, compatible with raw materials such as PPR, PVC, PE and CPVC.
Its PPR pipe fitting moulds cover full specifications from 20 mm to 63 mm and support multi‑cavity customization. PVC pipe fitting moulds fit sizes from 50 mm to 160 mm, and PVC ball valve moulds are designed for anti‑corrosion pipeline accessories. Custom development is available for both standard and special‑shaped fittings including elbows, tees, reducers and flanges.
The company has served more than 3,000 pipe‑manufacturing enterprises nationwide, covering major pipe‑producing provinces such as Jiangsu, Zhejiang, Guangdong and Shandong. It also accepts export orders from Southeast Asia and the Middle East, providing English‑language supporting documents and anti‑rust sea‑worthy packaging for exported moulds.
Supported by comprehensive pre‑sales and after‑sales services, the company provides 2D/3D solution design and cost‑cycle estimation for custom plastic pipe fitting moulds. Drawing on 18 years of expertise, it optimizes product structures to reduce material consumption. Three cooperation modes are available: drawing‑based, sample‑based and 3D‑drawing‑based development. After mould opening, trial‑molding is carried out to verify dimensional accuracy and sealing performance. Small‑batch injection molding subcontracting service is also offered.
24‑hour online technical support is provided to remotely resolve production issues such as sink marks and difficult demolding. Quick replacement of stocked wearing parts is available, and mould structural optimization can be implemented for product upgrades.
In terms of manufacturing technology, PPR pipe fitting moulds, PVC pipe fitting moulds and PVC ball valve moulds adopt dedicated mould steel with standardized heat‑treatment for enhanced wear and corrosion resistance. Conformal cooling channels are applied to shorten molding cycles, and balanced gating design ensures uniform wall thickness and stable sealing of pipe fittings.
Ventilation and core‑pulling structures are optimized for the characteristics of PVC material to minimize bubbles and flash defects on finished products. Multi‑cavity moulds deliver stable mass production with controllable reject rates.
The enterprise holds multiple patents for pipe‑fitting mould structures. It excels in developing complex flared and electro‑fusion pipe fitting moulds, proactively avoiding common industry pain points such as water leakage and dimensional deviation.
Possessing multiple practical patents for pipe‑fitting mould structural design, the technical team is proficient in developing high‑difficulty moulds for flared, electro‑fusion and hot‑melt‑specific pipe fittings as well as complex multi‑way pipe fittings. Potential mass‑production problems including water leakage, dimensional deviation and low molding efficiency can be addressed in advance.
Targeting pipe manufacturers, injection‑molding enterprises and foreign‑trade traders, Shaoxuan Mould delivers one‑stop solutions covering mould development, sample testing and injection molding. By cutting out intermediate links, it achieves outstanding cost‑performance. With stable production capacity, mature technology and long‑term after‑sales support, the company keeps supplying reliable mould products for global clients, including pipe fitting moulds, plastic pipe fitting moulds, PVC pipe fitting moulds, PVC ball valve moulds and PPR pipe fitting moulds.
