As a core equipment for the production of hollow plastic products, the price of extrusion blow molding molds is affected by multiple factors such as material selection, product specifications, number of cavities, structural complexity, supplier region, and customization needs, with a large price range. Based on the current market conditions (data source: 2025 industry quotations and supplier information), this article takes US dollars as the pricing unit to conduct a detailed analysis of its price composition and influencing factors, providing reference for purchasing decisions.
I. Core Influencing Factors and Corresponding Price Ranges
(1) Mold Material: Basic Source of Cost Difference
The material of extrusion blow molding molds directly determines their manufacturing cost, durability, and application scenarios. The price difference between different materials is significant, which is one of the core factors affecting the total mold price.
- Aluminum Alloy Material: The first choice for cost-effectiveness, suitable for small and medium-batch production and simple-shaped products. Aluminum alloy has low processing difficulty, good thermal conductivity, and relatively low cost, with a unit price usually between 300-2000 US dollars. For example, the quotation of aluminum alloy molds for simple hollow products such as 500ml-3L HDPE milk bottles and beverage bottles is mostly concentrated at 800-1500 US dollars per set; the price of molds for small hollow children’s toys is lower, and some basic models can be as low as 300-600 US dollars.
- Ordinary Alloy Steel (such as P20, 1.2311): Suitable for medium-batch production, with better wear resistance than aluminum alloy, and the price range is 1500-5000 US dollars. Such molds are often used for products with certain requirements for mold life, such as oil pots and laundry detergent bottles below 10L. A typical quotation is about 2500-3500 US dollars per set for 10L HDPE oil pot alloy steel molds.
- High-end Alloy Steel (such as H13, M300, M340): Suitable for mass production and high wear resistance scenarios. After quenching, nitriding and other strengthening treatments, the service life can reach more than 1 million times, and the price is mostly above 5000 US dollars. For example, the quotation of molds using H13 steel for high-frequency production such as automotive hollow parts and 200L chemical barrels is usually 8000-20000 US dollars; the price of high-end molds dedicated to 1000L IBC barrels can even reach 66000-82000 US dollars per set.
(2) Product Specifications and Structural Complexity: Key Variables of Price Fluctuation
The mold price is positively correlated with the volume, size, and structural complexity of the molded product. The larger the product and the more complex the shape, the higher the mold design difficulty, processing accuracy, and material consumption, and the price will rise accordingly.
- Small and Simple Products (volume ≤ 5L, no complex structure): Such as 500ml beverage bottles and 1L laundry detergent bottles. The mold structure is simple (mostly two-piece split molds), and the price range is 300-3000 US dollars. Among them, the standard 500ml PE bottle mold is about 600-1000 US dollars, and the 1L HDPE bottle mold with simple patterns is about 1000-2000 US dollars.
- Medium-sized Regular Products (5L ＜ volume ≤ 50L, medium structure): Such as 5L oil pots and 20L chemical barrels. It is necessary to consider wall thickness uniformity and demolding convenience, and the mold price is 3000-15000 US dollars. For example, the quotation of 5L automatic blow molding oil pot mold is about 4000-6000 US dollars, and the 20L HDPE chemical barrel mold is about 8000-12000 US dollars.
- Large and Complex Products (volume ＞ 50L, including special structures): Such as 120L-220L plastic barrels, children’s safety seats, and automotive hollow parts. The mold needs to integrate temperature control, exhaust and other modules, with high processing accuracy requirements, and the price is mostly above 15000 US dollars. Among them, the 200L standard chemical barrel mold is about 15000-20000 US dollars, the 1000L IBC barrel mold is 66000-82000 US dollars, and the customized mold for automotive hollow parts with special-shaped structures can reach 20000-50000 US dollars.
(3) Number of Cavities: Balancing Factor Between Production Efficiency and Cost
The number of cavities determines the single-batch production efficiency. Multi-cavity molds can significantly improve production capacity, but the design and processing difficulty increase, and the price usually increases stepwise according to the number of cavities (not a simple multiple relationship).
- Single-cavity Mold: Suitable for small-batch production or large-sized products, with the lowest price. The single-cavity mold for small and simple products is about 300-2000 US dollars, and the single-cavity mold for large and complex products is about 8000-20000 US dollars. For example, the single-cavity 2L laundry detergent bottle aluminum alloy mold is about 800-1200 US dollars, and the single-cavity 200L chemical barrel alloy steel mold is about 15000-18000 US dollars.
- Multi-cavity Mold (2-4 cavities): The mainstream choice, balancing efficiency and cost, and the price is 1.8-3 times that of a single-cavity mold. For example, the two-cavity 500ml beverage bottle mold is about 1500-2500 US dollars, the four-cavity 1L HDPE bottle mold is about 2499-4000 US dollars; for medium-sized products, such as the two-cavity 5L oil pot mold is about 7000-10000 US dollars.
- Multi-cavity Mold (≥6 cavities): Suitable for mass standardized production, only applicable to small and simple products, with a high price. For example, the six-cavity 500ml mineral water bottle mold is about 5000-8000 US dollars, and the eight-cavity small toy accessory mold is about 8000-12000 US dollars.
(4) Supplier Region: Regional Differences in Labor and Technical Costs
Suppliers in different regions have different labor costs, technical levels, and production scales, resulting in obvious regional differences in mold quotations. Among them, Chinese suppliers occupy the mid-to-low-end market with cost advantages, and European and American suppliers dominate the high-end customization field.
- Chinese Suppliers: Significant cost-effectiveness advantage, covering low, medium and high-end markets, with prices 30%-50% lower than those in Europe and the United States. Basic aluminum alloy molds are 300-2000 US dollars, mid-to-high-end alloy steel molds are 5000-20000 US dollars, and large and complex molds are 20000-82000 US dollars, which are the mainstream global purchasing choice.
- European and American Suppliers (the United States, Germany, etc.): Leading technology, focusing on high-end customization and high-precision molds, with high prices. Basic molds are about 1000-3000 US dollars, mid-to-high-end molds are 15000-50000 US dollars, and large and complex customized molds can reach more than 80000 US dollars. Their advantages lie in more guaranteed mold accuracy, service life and after-sales service.
- Southeast Asian Suppliers: Prices are slightly lower than those in China, but production capacity and technical level are limited, mostly focusing on low-end simple molds, with quotations of about 200-1500 US dollars, suitable for ultra-small batch and low-precision demand scenarios.
(5) Customization Needs: Main Source of Additional Costs
Customization needs include product structure customization, process optimization, material upgrading, and after-sales service, which will increase mold design, research and development, and production cycles, leading to a price increase of 10%-50%.
- Design Customization: For the mold design of special-shaped products, an additional design fee of 500-3000 US dollars is required, and the design fee for complex structures can reach more than 5000 US dollars.
- Process Customization: Such as special processes such as rotating die heads, multi-layer co-extrusion, and high-precision temperature control, the mold price increases by 20%-40%. For example, the ABA multi-layer film mold with a rotating die head is about 1300-4800 US dollars, and the high-precision medical product mold is about 8000-15000 US dollars.
- After-sales Service: Including 1-3 years of warranty, on-site installation and commissioning, and mold maintenance services, the price increases by 10%-20%, but it can reduce subsequent use costs.
