Injection Molding Equipment

Save outsourcing and shipping costs by bringing plastic injection molding equipment in-house
By Ann Lette Adding injection molding machinery to a business operation can raise profits by eliminating the outside supplier. Having parts when you need them and controlling the quality in-house speeds production. Small injection molding equipment is cost effective for small and medium needs while large-scale production models are available for mass production of larger parts or quantities.

Injection molding machines work by melting plastic resins and injecting them into a specially designed mold. Vertical and horizontal designs allow placement in space available. Knowing which machine and type of plastic depends on the application requirements; here are a few guidelines to consider:

1. Injection molding equipment must scale to meet production quantities.

2. Flexible injection molding equipment allows fast mold changes for multiple parts.

3. Multiple small injection molding machines save space over larger units.

Choose plastic injection molding equipment that works best for your business operation

Plastic comes in thermoplastics and thermoset plastics. Thermoplastics allow melting and shaping multiple times, which reduces waste and is easily recycled after use. Thermoset plastics are chemically altered once molded. Misshapen or out of specification parts can't be run through the injection molding machinery a second time. Many parts are acceptable from either material, but special requirements usually need thermoset mixtures.

Compare electric injection molding machines with hydraulic models for best ROI

Hydraulic injection equipment has been the standard for decades but newer electric models are beginning to take over. Electric models cost more initially, but are cheaper to install and maintain. Hydraulic models require oil and more maintenance, however, many in the industry believe higher-pressure applications are better achieved with hydraulic injection machines.
Try:  Milacron Inc. builds and supports a large selection of hydraulic horizontal and vertical injection molding machines. Electric models and hybrids are the focus at Stork Plastics Machinery to save operating costs and conserve power consumption.

Buy used injection molding machines to lower costs

Buying used equipment enables you to get more machine for the money. Injection molding equipment has a long lifespan and is easy to modify to meet the needs of your business. A used injection molding machine is especially effective in small production applications where return on investment is tighter.
