China has established itself as a major manufacturing hub for plastic moulds, including PET preform mould and bumper mould. With its skilled workforce and cost-efficient production capabilities, China offers an appealing option for companies looking to source moulds overseas. PET plastic bottles often start as preforms that are created using injection moulding tools like those offered by plastic mould manufacturers.
However, buying moulds from China also comes with risks around quality control, intellectual property, production schedules, and other factors. Following the right process can help ensure you receive high-quality moulds on time and on budget.
This guide will walk you through the key steps for successfully purchasing PET preform mould and bumper mould from China. The front and rear bumpers found on today’s cars and trucks are produced using specialized moulds from companies such as this China-based automotive mould maker.
Overview of the Plastic Mould Industry in China
China’s mould industry took off in the 1990s and 2000s as manufacturers moved production offshore to take advantage of lower costs. According to data from the China Die & Mould Industry Association (CDMIA), the industry generated over $32 billion in revenue in 2021, accounting for around 30% of the global mould market.
The major mould manufacturing hubs in China include:
- Guangdong province: Major export center with thousands of mould companies located in Guangzhou, Shenzhen, Dongguan, and other cities. Key industries served include automotive, medical devices, electronics, home appliances, and more.
- Shanghai: Home to mould makers serving sectors like automotive, aviation, electronics, plastic toys, and precision equipment.
- Jiangsu province: Key production base for moulds used in household items, recreational products, medical devices, and small appliances.
Within China’s mould industry, companies have developed extensive capabilities around PET preform mould and bumper mould:
- PET preform mould: China supplies over 80% of the global demand for PET preform moulds used in plastic bottle production. Major PET mould clusters are located in Guangdong, Zhejiang, Jiangsu, and Shandong provinces.
- Bumper mould: Chinese suppliers manufacture high volumes of quality bumper moulds for international automakers. Leading bumper mould manufacturers are concentrated in the Guangdong, Shanghai, Beijing, and Jiangsu regions.
Buying moulds from China offers proximity to manufacturing, experienced suppliers, cost savings, and other benefits. However, buyers need to follow the right process to overcome language barriers, vet supplier quality, protect IP, and manage logistics.
Step 1: Define Your PET Preform Mould and Bumper Mould Requirements
The first step is gaining a clear understanding of your specifications for the PET preform mould or bumper mould:
- Product design: Provide 3D CAD models, technical drawings, and design specifications to the supplier. Make sure the supplier fully understands your product design needs.
- Output and efficiency goals: Define your required production output volumes, cycle times, cavitation needs, and other efficiency metrics. This will impact mould design parameters.
