Introduction
Quality control is essential to sustain product reliability and performance in the rapidly changing plastic and polymer market. The melt flow index tester, or MFI, is a vital instrument that measures thermoplastic materials’ flow characteristics, guaranteeing that polymers utilized in pipe production, injection moulding, and extrusion process comply with industry requirements.
Choosing the proper melt flow index machine can be a game-changer for companies. In this guide, we will assist you in comparing small-scale vs. large-scale MFI testing machines, their differences, cost, and the best melt flow index tester manufacturers.
What is a Melt Flow Index Tester?
A melt flow index tester tests thermoplastic materials’ melt mass-flow rate (MFR) and melt volume-flow rate (MVR). It gives information on the plastic resin’s viscosity under given conditions, which is vital for ensuring quality and performance consistency.
Selecting the Proper Melt Flow Index Tester for Your Business
Depending on the scale of your pipe manufacturing facility, your pipe testing equipment needs will vary. Here’s how small-scale and large-scale producers can choose the perfect MFI testing machine:
For Small-Scale Pipe Manufacturing Plants:
- Need miniature and budget-friendly melt flow index machines.
- A moderate frequency of testing makes simple MFI testers appropriate.
- Need low-cost solutions with simplicity of use.
For Large-Scale Pipe Manufacturing Plants:
- Need high-precision polymer melt flow testers.
- Need automated functionalities and high-capacity performance capabilities.
- Need to meet ASTM D1238 and ISO 1133 standards.
