Products and Technologies

Blow-molding machinery

Shengmei’s principal products are extrusion blow-molding machines, identified in company and directory materials through model families such as the PBA series for smaller hollow containers and the PBLL series for large containers.

Extrusion blow molding generally involves the following sequence:

Plastic pellets are melted in an extruder.
The molten polymer is shaped into a tubular parison.
A mold closes around the parison.
Compressed air expands the parison against the mold cavity.
The formed container is cooled, opened, and removed.
Excess flash may be trimmed or recycled, depending on the product and machine configuration.

This process is suitable for containers with handles, irregular geometries, wide openings, and relatively large volumes. It is distinct from injection blow molding and injection-stretch blow molding, which use different preform and forming arrangements and are commonly associated with specific bottle types and higher-volume applications.

Size range and material capability

The reported capacity range extends from approximately 5-milliliter containers to hollow products of roughly 1,000 liters. Such a span places the company’s equipment across several technically different segments:

Small bottles and containers, where cycle time, dimensional consistency, and multi-cavity productivity are significant.
Medium-sized packaging, including household, personal-care, and industrial containers.
Large containers and tanks, where melt strength, wall-thickness control, cooling, mold handling, and structural integrity become more demanding.

Materials identified in the company’s product descriptions include:

Polyethylene, particularly grades used for bottles, jerrycans, and industrial containers.
Polypropylene, where higher temperature resistance and stiffness may be required.
Polyvinyl chloride, subject to appropriate processing and ventilation controls.
PETG and polyurethane for specialized hollow products and packaging applications.

Actual material suitability depends on polymer grade, additives, melt strength, rheology, mold design, parison programming, temperature control, and the intended performance of the finished article.

Machine-head configurations

The company describes single-, double-, triple-, four-, and higher-head configurations, extending to systems with as many as eight heads. Multi-head machinery can improve output by producing several articles per cycle, although its economic benefit depends on container size, mold arrangement, product uniformity, changeover frequency, and the available extrusion capacity.

For processors, the choice between a single-head and multi-head machine involves a balance among:

Required production volume.
Container size and weight.
Number of product variants.
Mold and tooling cost.
Material distribution requirements.
Changeover time and operational flexibility.

Automation and auxiliary systems

Blow-molding production normally requires auxiliary equipment such as cooling systems, air compressors, material handling units, mold-temperature controls, trimming equipment, and product inspection systems. Shengmei presents its machinery as part of an overall bottle-blowing solution, with automatic operation and electrical-control systems forming part of the equipment offering.

In-mold labeling is another technology associated with the company’s portfolio. It can reduce or eliminate certain downstream labeling operations and may improve label positioning and resistance to handling. Its practical use depends on label material, container geometry, mold design, electrostatic or mechanical label retention, and compatibility between label and packaging material.

Applications and End Markets

Shengmei’s machines are used to manufacture hollow plastic products for a range of end markets, including:

Food and beverage packaging: Bottles, jars, and containers for edible oils, sauces, dairy products, and other packaged goods.
Household and personal-care products: Containers for detergents, shampoos, cleaners, and toiletries.
Industrial packaging: Jerrycans, drums, tanks, and containers for chemicals, lubricants, agricultural products, and other industrial materials.
Automotive components: Selected reservoirs, ducts, and other hollow molded parts.
Pharmaceutical and medical packaging: Containers requiring controlled dimensions, material selection, and clean production conditions.
Specialty and large-volume products: Hollow articles and tanks requiring large machine capacities and specialized tooling.

The suitability of each application depends on regulatory requirements, barrier performance, chemical resistance, closure design, container strength, appearance, and the processor’s quality-management system.
