Manufacturing Process of Filter Plastic Parts at INDRO Workshop

In modern filtration manufacturing, plastic components such as end caps, cages, cores, and connectors play a decisive role in product performance and reliability. At INDRO, the production of filter plastic parts is not just a standard injection molding process—it is a carefully engineered system designed to meet the strict requirements of automated assembly and infrared welding.

This article explores the complete manufacturing process of filter plastic parts at the INDRO workshop, highlighting how precision, consistency, and efficiency are achieved at every stage.

Raw Material Selection and Preparation

The process begins with selecting high-quality raw materials that meet both mechanical and chemical requirements of filtration applications.

Common materials used:

• Polypropylene (PP) for chemical resistance and cost efficiency
• Polycarbonate (PC) for strength and clarity
• Polyamide (PA) for high-temperature resistance

Before molding, materials undergo:

• Drying to remove moisture
• Batch consistency checks
• Additive blending (if required for UV resistance or strength enhancement)

Proper material preparation ensures stable processing conditions and prevents defects such as bubbles, warping, or weak weld areas.

Precision Injection Molding

Injection molding is the core process in manufacturing plastic filter components. INDRO utilizes advanced molding machines and optimized tooling to produce high-precision parts.
