Understanding The Basics About Quality Control

The concept and importance given to quality control has continued to evolve with time. There was once a time where quality control was primarily used as a way to ensure customer satisfaction, But today quality control has also become a method of reducing costs and improving efficiency.


Firstly, quality control is the main factor in the manufacturing process. Creating a good reputation is linked to quality control. It comes as no surprise that manufacturers are often known in the industry for their quality assurance processes and customers are easily attracted to companies promoting high-quality standards.


Let’s take a closer look at the basics and identify what every manufacturer needs to know about quality control standards:


Advantages of Effective Quality Control


Identifying and eliminating any defects or inconsistencies in products before they reach the customer remains the main goal of quality control in manufacturing. A strong quality control system set comes with many important benefits for manufacturers. Some of these include:


  • Minimized Waste: Reducing defective products that would ultimately end up as waste
  • Compliance assurance: Ensuring products follow all regulation
  • Improved product safety: Defective products can have hazardous consequences.
  • Increased profits: Manufacturers don’t have to invest extra money rebuilding and refunding with minimized defects.


Taking extra time and effort to implement an effective strategy for monitoring quality can help your business in the long term.


Create a Quality Control Plan


A quality control plan includes the entire manufacturing process i.e every tool, specification, technique, control method, and reaction plan. This outcome ensures that each step in the manufacturing process is mapped out and structured in a way that creates a quality final product as efficiently as possible.


An effective quality control plan should include the following: 


  • Teaming up with members of each department, from engineers and manufacturers to quality control specialists and sales representatives and streamlining the processes.
  • Review part drawings to identify key specifications
  • Create a  clear process flow diagram to map out the product’s journey from start to finish in detail
  • Make a list of key processes and tools used to manufacture the part
  • Analyze the measuring equipment and techniques associated with specifications


List out the sampling size, control methods and reaction plans

With quality control plans in place, they can serve as living documents that help evolve as processes, equipment, and other factors are updated. This plan should serve as a foundation for your manufacturing process and be referred to frequently throughout the product journey.


Provide the Right Documentation


Manufacturers often have verticals and create products that are used across a wide range of industries. In such a case, each industry has to follow different regulations and different quality assurance protocols to meet the standards of their field.Therefore, it is important for manufacturers to consider providing a variety of quality control documentation to meet the regulations of the industries they serve.

Selecting the Right Seal Material the Easy Way

With the range of different materials available for seals, choosing the right seal material can seem intimidating.  In this blog, we directly address this issue in a simple manner. Here is how you can take the help of the acronym ‘TEMP’ to choose the correct material for an application:


  1. “T”  for Temperature

Different types of seal material offer a different range in temperature,from low to high.  Below are some popular seal materials offer the following ranges (Fahrenheit):

  • EPDM (EPM) -70 to 250
  • Fluorosilicone (FVMQ)  -100 to 350
  • Nitrile (NBR)  -30 to 250
  • Silicone (VMQ)  -60 to 400
  • Fluorocarbon (FKM) -15 to 400


  1. “E” for Environment

Seals are bound to be exposed to all types of environments.For instance, if the environment involves exposure to sunlight, EPDM is a good choice.  However,  in this type of environment, you would want to avoid the use of Nitrile in direct sunlight.


  1. “M” for Media

When selecting a compound, it is crucial to consider the media that will come in contact with the seal.  For example, Nitrile is known to perform very well with oils. However, it is best to avoid natural rubber with oils.


  1. “P” for Pressure

Pressure has to be considered an important part of the equation as well. One,  consider hardness (durometer), as it may be required where there is a large gap between the mating parts in a static application or to resist extrusion in dynamic designs.

Second, compare the at-rest vs. operating conditions to get a working idea of the long-term compression set properties of a given material.  When it comes to hardness and compression set, properties will vary among the elastomers and within the family of each one as well.

When picking a seal for an application, finding the best possible sealing material is the key. Always remember, there will be variations in performance within each family of rubber materials.  Although this article doesn’t touch on 100% of the factors to consider, we hope the introduction of TEMP will give you a headstart about your selection.


At Harkesh Rubber, we have a wide range of elastomers to fit the needs of your ‘TEMP’ requirement.  In addition to the TEMP acronym, our team of application engineers have extensive experience in engineering custom solutions as per your requirements.  Email us at [email protected] or give us a call +91-22-40060400 to place an inquiry.


Increasing Demand for Medical Grade Seals To Cope with COVID-19 Crisis

The influx of coronavirus patients has caused the medical industry to heavily rely on the production of rubber parts and seals to cope with this current healthcare crisis. To be eligible for use in healthcare, these medical-grade seals have to meet high FDA and ISO standards, as well as undergo rigorous testing.

Medical grade seals are critical in a wide range of life-saving and health improving applications that have enhanced the medical industry as a whole. Let’s take a closer look at how these seals and devices are being utilized during this health crisis now.


Personal Protective Equipment


The outbreak of the COVID-19 virus has led to a drastic increase in the demand for Personal Protective Equipment (PPE) in the medical industry. Medical grade seals play a huge role in the effectiveness of PPE where there is a significant requirement for sealing against harmful bacteria, viruses, and other pathogens to protect healthcare workers and their patients from being infected and infecting others. At the moment PPE is necessary for reducing the spread of COVID-19


Medical grade seals are essential for proper shielding and protection against contamination. For long term usage, advanced protective gear that depend on medical-grade seals include:


  • Powered and supplied air respiratory protection
  • Vented
  • Eyeshields
  • Half/Full face respirator


Ventilators and Medical Devices


Other medical equipments that have high utility at the moment are ventilators and testing devices. This medical equipment require many rubber parts and seals for engineering. Medical grade seals in ventilators and other equipment must be biologically compatible with the environment to comply with FDA regulations and to be suitable for patient use.


Biocompatibility is a term used to describe the ability of a material to perform properly by exhibiting superior compatibility with human tissue and body fluids and an extremely low tissue response when implanted. For example, silicones are odorless and tasteless, they do not support bacteria growth and stain or corrode other materials. In ventilators, this is extremely important to avoid further complications and disruptions with treatment.


In addition to producing parts and seals for ventilators and testing devices, Harkesh Rubber medical seals are also designed for a variety of other medical applications that are still needed right now, such as medical pumps, IV components, feeding devices, and implants.

Stepping Up the Supply Chain After Coronavirus

The disruptions caused by the COVID-19 pandemic are challenging businesses to think in unique and different ways. The virus outbreak has left deep impacts on the supply chain globally. Companies across the globe have been struggling to streamline their supply chains to secure immediate operations. There is pent-up demand waiting to be met for which companies have to pull up their socks and make the necessary changes to keep up in times of Covid-19 and more importantly, post-it.


Given the shifting nature of running everyday operations, companies will have to ramp up supply chains now and in the years to come, toabsorb the shock waves and lower the post-Corona impact. Companies not only have to address the shifts but also incorporate these shifts as a part of running the supply chain to meet demands seamlessly.


Have a look at some of the strategies and investments that you must consider to keep your supply chain up and running in the years to come:


1) Identifying Weaknesses


It is important to focus on areas that are particularly vulnerable and plan ways to cope or make up for these weak spots. Although important, optimizing by cutting down on costs and increasing asset utilization aren’t enough to handle the post- corona shock wave. To strengthen the supply chain and improve efficiency, it is essential to identify your problem areas first and work to improve them.


2) Multi-scenario Planning


Due to the outbreak of the virus many manufacturers offshore were shut down due to the spread of the virus. In countries like China and Italy, where some of the largest rubber manufacturers are located, company shutdowns were enforced and many orders were unable to be fulfilled. Sourcing locally withHarkesh Rubber alleviates the uncertainty of offshore issues.


3) Technology Driven Operations


Investing in a technology-driven dashboard that provides real-time information via an appcould be a good option for retailers to explore. Ensuring smooth material handling, along with adequate manpower availability, is another area that needs to be reviewed and plugged.


Providing a seamless journey for consumers through a mix of digital and physical infrastructure will require the backing of a strong supply chain. COVID-19, in all its volatility and stress, has opened up opportunities to take a hard look at the entire supply chain and reimagine it for tomorrow’s needs. At Harkesh Rubber, we have invested in high-quality rubber injection machines and other technological capabilities that allow us to improve our in-house operations significantly.
