5 Things You Need to Get the Most Accurate and Timely Injection Molding Quote

If you are planning a plastic injection molding project, and want to ensure excellence and timelines in your product delivery - review these following five considerations to make certain the result is exactly what you need.

1) Do 2d part drawings and 3d cad models exist?

The first question to ask yourself is this; Are you replacing an existing or similar product? Which means there may already be 2d drawings and cad models to work from.

If you do not have 2d part drawings or 3d cad models of the part, these should be provided. The 2d part drawings and 3d cad models provide detailed information on the size and complexity of the part.  

This is really necessary because words can always be interpreted differently, and details can be missed. This could make for significant differences in mold design, as well as cost. 

When done in this way - you can give the plastic injection molder the ability to access the part from a mold design perspective, to define parting lines, and draft angles for proper ejection and gate locations. This will protect and maintain the manufacturability of your parts.

2) What is the application for your product and its material?

It is important for your injection molder to know the end application, and usage conditions.  These include variables such as temperature, chemical contact and resistance. It also includes; 

  • Applied stresses during use 
  • Transparency/opacity 
  • Color, aesthetics
  • Water absorption
  • Lubricity and wear resistance

Your injection molder can then help to recommend a material base properly suited for your application. This is important for the plastic injection mold design stage because different resins have different shrinkage rates, levels of corrosiveness, etc. It is not practical to change resins after the mold has been fabricated.  

This also relates to the type of manufacturing environment required to manufacture the product, for example a clean room may be required.

3 Must Ask Questions Before Choosing an Injection Molder

When choosing an injection molder for manufacturing of plastic medical devices or other specialty projects, there are mandatory guidelines that should be used to determine how to choose the right company.

1) What Quality Management System/Quality Standards do they Follow?

It is critically important to assure there is a robust Quality Control system in place. This shows that the company monitors the effectiveness of their supply chain and demonstrates traceability related to regulations of materials and finished goods.   Correct documentation, data monitoring and storage is critical to any quality injection molding manufacturing process. 

To this end, some things to remember include:

Asking your injection molder what quality management certifications they have and if that meets your requirements. For instance; FDA registration, or ISO 13485:2003 are common requirements for medical devices and components.

If these systems are in place they require a certain amount of documentation, assessing and minimizing of risks, as well as product realization.  

These types of quality certifications also show that this injection molder takes their business seriously, which means they have higher-than-average quality standards.

 2) Can They Support your Entire Product Life Cycle?

This means can they offer you a single source for procurement? This requires having a company that can provide services from the design phase through production - then have it immediately shipped out the door from the factory. 

Will they provide design and development services either as your design team - or enhance your in-house staff. They offer insight and recommendations based on their own experience, they know the industry best practices, and then look at design for manufacturability.
