If you’re considering a plastic part or mold for your production needs, you may be wondering what you need to request a quote. 

In this blog post, we will discuss the benefits of plastic injection molding, what to have ready when getting a custom injection molding quote, and factors to consider when choosing an injection molding company.

After reading this blog post, you will have a better understanding of how to get an accurate and efficient plastic custom injection molding quote.

Plastic injection molding is an incredibly useful and cost-effective process for creating custom plastic parts and components. It involves the use of melted plastic that is heated to a liquid state, then injected into a mold to create the desired shape. After the plastic has cooled, the parts are removed from the mold and ready for use.

This process offers many advantages, including cost savings when compared to other manufacturing processes.

Plastic injection molding also allows for high levels of accuracy in terms of product dimensions, as well as a wide variety of shapes and sizes that can be produced with minimal effort. Furthermore, this method produces high-quality parts with consistent surface finish and minimal waste material.

Detailed drawings or designs of the parts you want to create will be tremendously helpful for getting an accurate estimate. You can work with the molding company who can assist in creating these designs and drawings but if you already have them ready, providing CAD files will help speed up the process. This should include any special features or design elements that are unique to your project.

Be sure to include measurements, specifications, unique design elements or special features so that the molding company can accurately calculate the cost of production.

The custom injection molder will need to know the number of pieces you need to produce. Knowing how many pieces are needed will help in calculating setup costs and other fees associated with production runs.

If the quantity you need is less than 1,000 pieces, then custom injection molding is likely not going to be a cost-effective route, as it is best for high-quantity production needs.

Plastic injection molding offers a range of benefits for businesses looking to produce custom plastic parts and components.

  • Short Lead Times – Lead times are typically quite short, so you can get your parts faster than if you were using other methods. Automation capabilities allow you to streamline production and reduce costs even further.
  • Design Flexibility – The range of sizes, shapes, and colors that you can achieve with plastic injection molding is also impressive. You’ll be able to produce parts that have complex geometries or intricate details without sacrificing accuracy or repeatability. The precise control over the size, shape and finish can eliminate the need for secondary operations such as painting or finishing. Additionally, injection molding can be used to create complex shapes that may not be possible with other manufacturing processes.
  • Cost Effective -The cost per part produced through plastic injection molding is often very low compared to other methods. And since there are so many types of plastic available for use in this process, you’ll have plenty of options when choosing the best material for your project. Do keep in mind that there is a tooling cost involved which can range anywhere from around $15K – $100K or more for projects within most molding company capabilities. While custom injection molding is a cost effective method, it’s important to understand what goes into the costs that are involved.


This process offers many advantages that make it an attractive option for businesses and entrepreneurs who need to create a large number of parts in a short amount of time. Do understand that all three of these key advantages are dependent on the quantity being produced.

When it comes to finding a quality injection molder to get a quote from, it pays to do your homework.

Research different injection molding companies to find one that is experienced and reliable. Look for companies that have a proven track record of producing high-quality parts and components and ask for references and samples of previous work.

It’s also important to check the website to see if the company is certified and compliant with industry standards. Also ensure that the company is using quality materials, machinery and processes to produce parts with high precision and accuracy.

By considering these factors, you can be sure to choose a reliable and experienced injection molding company.

How to Ensure High Quality Injection Molding: 6 Best Practices

The widely used practice of injection molding is a highly versatile and efficient manufacturing process that delivers high-quality plastic components and products. Market segments like defense, medical, and pharmaceutical rely on plastic injection molding to create products and components that use flame retardants, offer chemical resistance, and can be sanitized enough to use in medical devices.

With so much on the line, knowing you have the highest quality injection molding possible is vital. So, consider these best practices when looking for high-quality injection molding services.

Best Practices for Quality Injection Molding

1. Design for High-Quality Injection Molding

The success of your plastic component or device starts with a well-designed injection mold that adheres to the best practices for injection molding. Design for Manufacturability (DFM) is a crucial principle that considers the manufacturing process during the design stage. By selecting an injection molding partner that offers DFM, you will get the following:

  • Improved moldability: By considering factors such as part geometry, wall thickness, draft angles, and undercuts, potential design issues can be identified and resolved early on. This results in a more moldable product design with reduced risks of manufacturing defects.
  • Cost savings: By addressing manufacturability concerns at the design stage, potential issues that could result in expensive tooling modifications, production delays, or high scrap rates can be avoided, saving you money.
  • A faster time-to-market: DFM makes things more efficient, reducing the need for multiple iterations and modifications. This allows you to bring your products to market faster.
  • Improved overall product quality: By addressing potential manufacturing challenges and optimizing the mold design, the risk of defects minimizes, resulting in a better high-quality injection mold.

The Role of Design for Manufacturability in Achieving an Optimized Mold Design

The role of DFM can't be overstated when creating a high-quality injection molding product. So, here's a dive into how it works.

A moldability analysis assesses the design's compatibility with the injection molding process.

Design modifications are made to ensure consistent wall thickness, dimensional stability, and easy ejection. The DFM team then controls for other things that could complicate the molding process. It optimizes the mold design by considering the arrangement of mold cavities, cooling channel design, venting, and ejection mechanisms.

The process is further optimized by deciding on the appropriate injection molding parameters, such as injection speed, temperature, and pressure profiles. By fine-tuning these injection molding process parameters, DFM ensures you get the most high-quality injection molding on the market.

  • Risk mitigation

Detecting surface defects before you go into production ensures superior visual surface quality and helps reduce costs by reducing scrap rates, rework, and customer complaints. Additionally, conducting thorough inspections of the mold and produced parts through visual inspection and functional testing ensures adherence to quality standards. It makes your final product safe, effective, and profitable.  

4. Material Selection

Not all plastics are made equally, and the right material selection determines your product or component's durability, functionality, and compatibility with the injection molding process. To create the highest quality plastic injection molding, consider the following:

  • Mechanical properties: Factors such as tensile strength and impact resistance determine whether or not the final product can withstand its intended purpose.
  • Chemical compatibility: Certain applications may involve exposure to chemicals, solvents, oils, or other substances. Knowing this is crucial in selecting a material that exhibits resistance to these chemicals.
  • Thermal properties: Melting point, heat resistance, and thermal expansion are critical material considerations in injection molding. Knowing if your plastic injection mold will be subjected to varying temperature and injection speed conditions is part of choosing the right material.
  • Regulatory compliance: Specific industries such as automotive or medical have material regulation standards for safety and reliability. Make sure your chosen material meets your product's legal obligation.
