The popular Section 179 deductions on equipment purchases have increased from 125,000 to $500,000 in 2013. This rapid deduction allows companies to deduct up to one half a million dollars in just one year without having to depreciate the equipment. The idea behind such a tax credit is to encourage companies to purchase new equipment […]

Shorts, Sinks, & Flash
During a recent discussion, a manager related to me that their most common defects are shorts, sinks, and flash. She then stated that this is inherent to the molding process could not really be changed. Shorts, Sinks, & Flash: Whenever these three are the top defects at a facility, it is because the molds are being filled too […]
Improving Process Efficiency – Packing Pressure
Process efficiency is one of the largest concerns in the industry today. Improving the efficiency and reliability of a process is a great way to reduce overhead, this post specifically addresses optimization of packing pressure. Packing Pressure Window: Assuming the transfer is developed with a 1st stage short shot, you should determine the minimum and […]
Improving Process Efficiency – Transfer
This is another installment in a series of posts on improving process efficiency. Using the appropriate transfer from 1st Stage Injection to 2nd Stage Packing will help reduce equipment wear and overall energy consumption. Regarding Energy: When you transfer when the mold is completely full, the pressure in the barrel increases sharply. This increase is caused by […]
Improving Process Efficiency – 1st Stage Injection
This is the first in a series of posts I will make on easy ways to improve efficiency and reduce costs. Reducing the 1st Stage Injection time is one of the easiest ways to reduce both the cycle time and energy required to inject the polymer. Regarding Energy: Increasing the rate of injection will increase the shear applied […]
