Buying Guide: How to Choose the Best PP Making Machine
Before diving into the specific models, it is crucial to understand the key metrics that define a high-performance PP making machine in 2026.
1. Power Consumption vs. Output
Energy costs are often the largest operational expense in melt-blown production. Look for machines that utilize advanced air heating systems and frequency converters (inverters). A standard efficient machine should consume between 30kW to 40kW per hour while delivering at least 3,500 pieces per day.
2. Automation Levels
The best machines feature fully automatic control systems powered by PLCs (Programmable Logic Controllers). This allows for “set and forget” operations where temperature, screw speed, and air pressure are automatically adjusted to maintain fiber diameter consistency, reducing the need for skilled manual labor.
3. Multi-Layer Capabilities
Single-layer filters are becoming obsolete for high-end applications. Top-tier machines, such as the 2E2M and 3E3M models, use multiple extruders (2 or 3) to create gradient density filters. This structure—loose on the outside, tight on the inside—drastically improves the dirt-holding capacity and lifespan of the filter.

Frequently Asked Questions
Q: What is the difference between 2E2M and 3E3M machines?
A: “E” stands for Extruder and “M” stands for Mold. A 2E2M machine has two extruders and two molds, allowing for dual-layer filters. A 3E3M machine has three of each, enabling the production of three-layer gradient filters, which generally have higher filtration efficiency and longer service life.
Q: What raw material is used in these machines?
A: These machines are designed to use Polypropylene (PP) granules. For the best results, specifically designed “Melt Blown Grade” PP with a high Melt Flow Index (MFI) is recommended to ensure ultra-fine fiber formation.
Q: Can these machines produce filters with different surfaces?
A: Yes. Most modern machines, including the 2e2mPP model, can produce smooth, orange peel, or grooved surfaces. However, some textures like deep grooves might require an additional carving machine or specific receiving rollers.
Q: How much space is required for installation?
A: A standard production line typically requires a minimum area of 50 to 100 square meters. You also need to account for ceiling height (usually at least 3.5 meters) to accommodate the extruder hoppers and air handling equipment.
