Our Engineering and Tooling Services - How We Use Them

Get to know our engineering and tooling services, including DFM (Design for Manufacturing). DFM is our technical and strategic advantage. We see the design planning stage as the most opportune time in the development process to consider how the end user wants a given product to function. When we understand this better, it helps us create a more robust design and enables us to produce higher-quality parts and ensure efficiency.

Technical Principles of Design for Manufacturability

Early Customer Involvement

Early customer involvement is crucial to ensuring a flawless and functional product. The DFM process typically begins with cross-functional collaboration between our team and the customer. From day one, our engineering, tooling, quality, purchasing, and plant personnel are actively engaged with the customer, getting their insights into how the end user will utilize the product. These are essential in determining the key features of the product that contribute to its functionality. 
Additionally, the customer provides context about the environment in which the final product will operate, helping us anticipate any variables that may affect its performance. This is an important conversation point as it ensures: 
* Holistic Design Reviews

All disciplines contribute, identifying risks and opportunities across the product life cycle. 

* Supplier Expertise 

Material vendors and component suppliers are consulted early, leveraging their technical expertise to optimize selection and manufacturability.

Advanced Material Selection

Material selection is a crucial first step in the plastic part design process, as it directly influences product performance, manufacturability, and overall cost efficiency. The selection begins with a thorough understanding of how the product will function in real-world conditions and involves evaluating mechanical properties, such as tensile strength, impact resistance, and flexibility, to ensure the product can withstand its intended load and stress.  Chemical resistance is essential for applications exposed to oils, solvents, or harsh cleaning agents, while environmental durability—such as UV stability for outdoor use or resistance to extreme temperatures—ensures long-term reliability of the final product.

Sustainable Engineering

Integrating sustainable engineering into every stage of the DFM has become a priority for many injection molding manufacturers. Designs are carefully optimized to minimize resin use without compromising performance, ensuring material efficiency from the outset.

Additionally, life cycle analyses assess recyclability, end-of-life options, and overall environmental impact to support customers in achieving their sustainability goals. For high-volume applications, hot runner systems are often employed to reduce waste and enhance efficiency, reinforcing our commitment to both cost-effectiveness and environmental responsibility.
