Marlborough Plastics Manufacturing Facilities

Our manufacturing facilities are located at 226 North Main Street in Marlborough, Connecticut.

Geometrical Possibilities

The most commonly used plastic molding process, injection molding, is used to create a large variety of products with different shapes and sizes. Most importantly, they can create products with complex geometry that many other processes cannot. There are a few precautions when designing something that will be made using this process to reduce the risk of weak spots. First, streamline your product or keep the thickness relatively uniform. Second, try and keep your product between 2 to 20 inches.

Equipment List

• Injection molding equipment 35 – 300 tons
• CNC machines
• Full in-house tool and die Facility

Our staff of skilled machine operators is ready at a moment’s notice to meet your custom injection molding and design needs.

The time it takes to make a product using injection molding can be calculated by adding:
Twice the Mold Open/Close Time (2M)
+
Injection Time (T)
+
Cooling Time (C)
+
Ejection Time (E)

Where T is found by dividing:
Mold Size (S) / Flow Rate (F)


Total time = 2M + T + C + E
T = V/R

V = Mold cavity size (in3)
R = Material flow rate (in3/min)
