Precision injection molding is an advanced and technical manufacturing technique. The process is suitable for industries needing high accuracy, such as pharmaceuticals, automotive, technology, and medical devices. The following guide can help you decide if it's the best option for your business and product needs.

How Does It Work?

The process is a form of plastic injection molding that's ideal for producing delicate parts that might break during standard injection molding. It's often used to replace metal pieces with plastic ones for lighter and more cost-efficient products. Lenses and moving or connecting parts are among those that get the most benefit from the process. It allows for precise repetition of design and quality without deviation. 

All aspects of the process are monitored and controlled, including position, speed, pressure, temperature, and thickness. Shrinking can occur during the precision injection molding process, but using replacement polymers and accounting for shrinkage in the design can maintain quality and accuracy.

What Are the Benefits?

Precision molding allows delicate parts with little room for error or deviation from the desired specifications to be manufactured on a large scale for lower costs. These pieces previously required specialized personnel and processes to be produced, but they can now be done by machine, often in one step. This leads to quicker turnaround times and the capacity for larger orders, and the use of plastic polymers leads to lightweight, durable products.

What Affects Precision?

Multiple factors impact accuracy, such as the material used. Certain plastics, like polyethylene, have a high shrinkage rate, while those with glass or other plastics added in stay truer in size. The mold's position and number of cavities can also affect the results, so they're calculated precisely for each piece. 

The accuracy of the design engineering affects the precision of the products, as the correct cavity size and thickness are crucial to producing usable parts. Proper positioning and the quality of machinery also determine the precision of the products.
