Guide to Testing the Quality of Plastic Chair Components


Investing in plastic chair is a smart decision because these furniture pieces are practical, durable, and versatile. There is more use for plastic chairs now than it did about a decade or so ago. This growing popularity of plastic chairs can be attributed to the improved manufacturing processes that greatly enhanced their overall quality, making them a good value for money.

Quality has been one of the issues with buying chairs made of plastic material. There is a misconception that they are poor in quality and won’t last very long. Well, that has changed now because recycled plastics and polypropylene (among other types of plastic materials) are now the go-to choice for furniture manufacturers, especially those looking for high-quality yet affordable chairs.

In this guide, you will learn about the different ways of testing the quality of plastic chair components that ensure longevity and durability At Maka Furniture, we follow a strict guideline and set of protocols at the end of the manufacturing and production process. We take his commitment to ensure that we have quality control in place to assure our customers that each piece is worth their money.

Standard Tests on Plastic Chair Components

The following are the series of tests we perform on plastic chair components and the overall chair to verify quality and durability. This will give you peace of mind that you will be getting a quality piece to use at home or for commercial purposes.

Melt Flow Index

The melt flow index test is a standard testing procedure for furniture and chair that is manufactured using the injection molding process. Identifying the metal flow is crucial to understand the behavior of thermoplastic during the molding process.

In this test, the plastic granules are melted before the plastic is poured onto the orifice for 10 minutes. The amount of plastic that comes out within that time period is weighed. The resulting weight is compared to the original amount to determine how much plastic is left. A poor melting flow is one wherein the plastic did not flow well and most of it was left in the container.

Moisture Analysis

Polypropylene and thermoplastic materials are considered highly resistant to moisture. This makes this type of plastic a popular choice in furniture manufacturing due to its ability to resist damage (since too much moisture can make the material vulnerable to damage). The high resistance against moisture is also critical in enabling plastic chairs to withstand extreme weather conditions such as rain, snow, and other sources of moisture.

A moisture analysis is important when testing the quality of plastic chairs to ensure that it can sustain damage. The plastic chairs are subjected to a variety of controlled testing conditions to expose it to extreme levels of moisture and its response. This test is also designed to measure the water content in the plastic material. Some types of plastic also have the tendency to absorb moisture when exposed to humid conditions. If this is the case, the final product could suffer from internal strains and overall poor quality as the material can be compromised from within.

Radiographic Test

This type of test is performed on plastic chairs that went through the injection molding process. This is another standard procedure for testing mass produced items like plastic chairs. In this test, the material or the final product is exposed to a beam of radiation such as gamma ray. The intensity of the radiation beam passes through the plastic material and onto the opposite end. This is collected into a data sheet for further testing.

The plastic chair is examined to see if some of the areas, especially where the radiation passed through, were thicker, thinner, or flawed. It is inspected to see any difference in the material after it was exposed to the radiation source. One of the indicators that it sustained damage from the radiation is if there are any dark spots on the surface of the material.

Additional Tests for Quality

You can also perform your own quality testing on the plastic chairs upon receiving them in the mail. This is an important step to ensure that they did not get damaged during the transit of the items. It is also important to ensure that no item has bypassed our quality control measures and you did not receive a faulty item.

The first thing you need to do is to take the chairs out of the box. Disassemble the pieces and check if all of the pieces are complete. Each piece of chair is wrapped in a bubble bag to prevent damage in the event of any bumps outside of the box during the transit of the items. Look for any signs of bumps and scratches on the outside of the chair.

We will provide you with some spare parts to replace any damaged or loose parts. It is also a good idea to test the load bearing capacity of the chair. The maximum weight of the chair is indicated in the box so make sure to check this accordingly. Make sure to place the chair on a stable surface before adding weight to it. After adding the weight, perform a physical test on the chair to see if it suffered any signs of damage, such as cracks or dents.

Final Words

At Maka Furniture, we strive to maintain the same level of quality and performance when we manufacture plastic chairs. We ensure that proper testing is done on our chairs after the final production to ensure that you get your money’s worth and that they can perform as expected. Also, if you can get a certification to attest to the quality of the chairs, that would be even better.
