What This Machine Actually Does<\/h2>\n

\"CraftsThe HGA Series Crafts and Special-Shaped Bottle Blow Moulding Machine is a professional two-step (two-stage) stretch blow moulding system designed for producing containers with non-standard or complex geometries. Unlike conventional single-step systems, the two-step process separates preform injection from the blow moulding stage entirely. Preforms are produced or sourced separately and then reheated and stretched within this machine to create the finished container. This separation gives manufacturers far greater control over wall thickness uniformity, material distribution, and output scheduling — particularly valuable when running short runs of specialised vessels or switching between different bottle formats across a UK packaging operation.<\/p>\n

Suitable for blowing baby feeding bottles, PP bottles, craft gift containers, and irregularly shaped vessels of varying sizes, the machine delivers consistent quality across all cavity configurations. The design accommodates container capacities from 1,000 ml up to 15,000 ml depending on the model variant, with neck diameters ranging from 40 mm to 168 mm. Whether a UK packaging converter needs to produce decorative glass-look PET jars or an OEM plastic parts manufacturer is scaling up PP bottle output, this platform covers both standard and bespoke production requirements without requiring a separate dedicated line for each product type.<\/p>\n<\/div>\n

Why UK Manufacturers Choose This Machine<\/h2>\n

Two-Step Flexibility<\/h3>\n

Decoupled preform and blow stages mean you can switch container formats, change cavity counts, or use third-party preforms without retooling the entire line. Run one SKU in the morning and a completely different bottle profile in the afternoon.<\/p>\n<\/div>\n

\n
\u2699<\/div>\n

Wide Container Range<\/h3>\n

From compact 1,000 ml baby bottles to large 15,000 ml craft or industrial containers, the HGA series spans a capacity range few competing platforms match. Maximum container height reaches 450 mm and diameter 240 mm, accommodating unusually tall or wide vessel profiles.<\/p>\n<\/div>\n

\n
\u26a1<\/div>\n

High Theoretical Output<\/h3>\n

Depending on model, rated theoretical output reaches up to 2,800 bottles per hour. The HGA.JS-4C114 four-cavity configuration is engineered specifically for high-volume scenarios where throughput-per-floor-area matters, without sacrificing surface finish on complex geometries.<\/p>\n<\/div>\n

Stable and Reliable Performance<\/h3>\n

The machine’s pneumatic, hydraulic, and cooling systems are independently regulated, keeping process variables stable across long production runs. Operating pressure sits at 7 kg\/cm2 for air, with a separate 5-6 kg\/cm2 blowing circuit, and cooling water flow is managed at 30 ltr\/min across most models.<\/p>\n<\/div>\n

Custom Tooling and Mould Support<\/h3>\n

We supply matched mould sets for all standard container profiles and accept bespoke mould specifications for craft, cosmetic, food, and specialty industrial bottles. Preform holder counts range from 40 to 488, and cavity configurations cover 1, 2, and 4 cavities depending on the model.<\/p>\n<\/div>\n

Energy-Efficient Heating<\/h3>\n

Max heating power reaches 85 kW on the larger ES-2C200 model, while actual running heating power in typical cycles is substantially lower — delivering cost-effective thermal performance even for UK facilities operating under rising energy costs. Cooling water temperature range of 8-12 degrees C is easily met by standard chiller systems used in British plastics plants.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Working Principle, Materials and Applications<\/h2>\n

\n

Two-Step Process Explained<\/h3>\n

In the two-step blow moulding process, preforms are manufactured independently — either in-house on a separate injection moulding machine or purchased from a specialist preform supplier. These preforms are then loaded into the HGA machine, where an infrared heating station brings them to the precise stretch temperature (typically 90-120 degrees C for PET). A stretch rod then extends the preform axially while high-pressure air inflates it radially into the mould cavity. Because heating and blowing are in separate machines, operators can stockpile preforms, run blow moulding at a different pace from injection, and switch container designs simply by changing moulds and preform specifications — a major advantage for UK converters managing multiple SKUs or seasonal packaging runs.<\/p>\n<\/div>\n

\n

Compatible Materials<\/h3>\n

The HGA Series is engineered to process PET (polyethylene terephthalate) and PP (polypropylene) as primary resins. PET is the most widely used material for clear beverage bottles, cosmetic containers, and food-grade packaging across the UK market. PP is preferred for opaque or semi-translucent applications including baby feeding bottles, personal care products, and certain pharmaceutical containers. For special-shaped craft and decorative bottles, colour masterbatch compatibility allows vivid, uniform colouration without surface defects. The clamping and stretching stroke parameters vary per model to accommodate the different melt behaviour and wall thickness requirements of these two resin families.<\/p>\n<\/div>\n
