Guide to Cost-Effective Mass Production - Injection Molding

Costs, quality control, and lead times are some of the most common concerns people have when it comes to mass production. These are valid concerns shared by companies and entrepreneurs that may be hard to overcome, and ordering your first batch can feel like a jump in the dark.

Finding the right manufacturing solution is critical since a seamless and cost-effective mass-production process can distinguish between a successful and a risky product launch. That’s where injection molding comes in. This versatile manufacturing process has become a go-to solution for established companies making products ranging from small, specific goods to large worldwide distributed parts.

According to Grand View Research, the global injection molding market was valued at $258.2 billion in 2020, and they expect it to keep growing in the following decade. If you want to learn everything about this technology before moving ahead, we invite you to check out this article covering all you need to know about Injection Molding.

This guide will help you understand how to use Injection Molding for mass production at the best costs. From ideation to design, prototyping, supplier selection, and manufacturing, we’ll cover all the critical steps in the process and provide practical tips and advice to help ensure your success.

Cost-effective Mass Manufacturing Guide

01 Ideation

At the conception of any product comes the design process. But before starting any design process, it’s essential to have a clear understanding of your product requirements. It’s necessary to consider factors such as the product’s intended use, target audience, and desired functionality. This information will help guide your design decisions and ensure that your final product meets your customers’ needs.

02 Design for Manufacturing

Once you clearly understand your product requirements, it’s time to consider design for manufacturing. DfM involves designing a product having the chosen manufacturing process’s limitations and capabilities in mind, so its production becomes as efficient as possible.

Some key design considerations for DFM in injection molding include:

• Geometry: Parts must have a consistent wall thickness to ensure even cooling and minimize the risk of warping or cracking.

• Material selection: Different materials have different properties, so choose the most suitable for your product requirements.

• Draft angle: Injection molded components must have a draft angle to allow easy removal from the mold.

• Gate placement: The location of the gate (where the molten material enters the mold) can affect the quality and appearance of the final product.

Design for Manufacturing, Assembly, and Manufacturability are critical in the cost-effectiveness of the general process. It can reduce unnecessary costs related to design issues and production difficulties considerably. Don't overestimate the importance of this process.

03 Prototyping

Prototyping is a crucial step in the injection molding process. It allows you to test and validate your product before production begins, saving you time and money in the long run.

To create a prototype, you can start by using a complimentary method, such as:

• 3D printing: Quick and inexpensive method. With 3D printing, you can easily create a simple prototype to test its design and usability.

• CNC machining: A more precise method to prototype, depending on your preferred material. CNC machining may help you get a more accurate prototype that will allow you to perform more tests.

• Vacuum casting: This method creates a high-quality prototype using silicone molds, but it may not be suitable for larger or more complex parts.

Choosing the correct prototyping method for your product will depend on several factors, including your budget, the complexity of your design, and the desired accuracy and functionality.

04 Finding the Right Supplier

Having a reliable supplier is critical for the success of your mass production process, as they will play a key role in determining the quality and consistency of your finished product.

When you look for a supplier for your injection molding needs, there are several essential qualities you should look for, including:

• Experience in your industry and with injection molding

• A strong reputation for quality and reliability

• The ability to handle the scale of your production needs

• A commitment to meeting tight deadlines and schedules

• Competitive pricing and a willingness to work within your budget

Finding the right supplier for your injection molding needs will require research and due diligence. On-demand manufacturing platforms such as Wikifactory saves you the time, costs, and hassle of this process by offering you Injection Molding services with quality-assured manufacturers.

05 Manufacturing Process and Quality Control

The manufacturing process starts with creating the mold to produce the desired part or product repeatedly. Some things that impact this process’s success, cost, and time include:

• The mold’s design.

• The material used.

• The injection molding machine.

• The experience from the injection molding manufacturer.

• The production process itself.

After the mold is ready and quality checked, the following steps are: material preparation, mold setup, filling the mold with molten material, cooling and solidifying the material, and finally, removing the finished part from the mold.

Quality control involves monitoring and adjusting various aspects of the process to ensure that the final product meets your desired specifications, starting with the design of the mold. It continues throughout the manufacturing process by monitoring and controlling the operations and continuously improving methods to ensure consistent quality.
