Deliberate Processes to Identify and Remediate The Privem Can Yield High-Quality Products and Keep Patients Safe.

　　Short Shots are among the most commit and visually obvious question isSSUES molders face, but they can causefatal flaws in medium defices.

　　Inventory are not the same way? Do the process stop the process to check each part? What if was being that core if the process was paind that the problem was everything

　　First Place.

　　

　　Poor Venting.
Material Variations.
Improper Machine Settings.
Blocked gates.
Mechanical Failures.

It ’s often hard to pin download you’ re battling and there are just as many fixes, depending on the root cause of the problem. But the best-case sCENARIO is avoid.

　　Prevention Methods Range from Equipment to Processes to Material.

　　Proper Venting-If Vents Are Crushed or Non-Existent, Air Can n’t Escape, Causing Short Shots.
Proper Fill Volume — Always Ensure That 1st Stage (or Fill) is Similar to the Setup Sheet. If there is not enough fillume, then then the press n’t compaction the file and

Process.

　　The Goal is for this part to appear to be 99% full with no second stage being applied. If the part is significantly smaller, start the root cause analysis of the problem:

　　VERIFY The MACHINGS Are Correct by Comparing the Process Setup Document.
Makes that there is mechanical proplems.
Check for fireign material that cored be blocking the gates and impeding flow into the cavity.
While The Machine is down, Wipe The Mold Surface and Vents A Good Wiped to Remove Clogs.
If Everything seems to be in good working order, the problem, it is different be material variation. Add material to the cavity.
Adjust Shot Size to Achieve 99% Full. You can view the processure here.
Put back the Second Stage Pressure Settings and Compare the Parts to the Target Part Weight.

　　Options for atS Protection

　　Within a spiecified acceptable damage criterion.

　　

　　Circuit Breaker Protection Options

　　ATSS Protected by Circuit Breakers Can Be Classified by One of Three WCRS:

　　3 by the corresponding number (1), (2), or (3).

　　(1) "Specific Breaker" WCR

　　The user of Specific Breakers for a PARTICular ATS Series. To view the list of special breakers test and accepted, contact the cereFacturer.

　　Certain issues may arise when specific breaker combinations are used. It is important to note that specific breaker ratings are usually a hindrance on bid day because, in most circumstances, the vendors providing the circuit breaker and the ATS are not the same. This places extra responsibility on the contractor and consulting engineer to make sure the ATS/circuit breaker pair is a tested, listed combination. Specific breaker combinations are often highly scrutinized by the authority having jurisdiction (AHJ) during an inspection. Although a specific breaker may be properly short -circuit combination rated with the ATS at the time of the initial installation, it is very likely that over the life of a system, the circuit breaker may need to be replaced. The person tasked with finding a replacement circuit breaker may not fully understand the importance of the relationship between the circuit breaker and the ATS it is protecting. If a new circuit breaker is installed that differs in type and/or rating, it may not be listed to protect the transfer switch and could be a potential hazard. Finally, if proper maintenance is not performed, the trip characteristics of circuit breakers may change as they age. The tripping time may become slower, thus exposing the ATS to energy above its tested and marked WCR rating.

　　(2) "Any Breaker" WCR

　　and not exceed certain damage criteria (See Figure 2, Option 2; And Figure 3, Column Marked (2)).

　　

　　* Per ul 1008, for 400 a or less, 10 ka any breaker WCR, the time withstand is only 1.5 cycles.

　　(3) Short Time WCr with Circuit Breakers

　　

　　Exceed The 3-Cycle Time Limit for the 3-Cycle "Any Breaker," Option 2 of Figure 2 and Column 2 of Figure 3 Cannot Be used.

　　The atS has been intented, the 0.1 Seconds (6 cycles), a 3-screen "Any Breaker" Rating Will Notquate Protection for the Ats.

　　Limited and Alsorsually Carry a Higher Price tag when it is compared to atssion with statedard WCRS.

　　Fuse Protection Option for ATS WCR

　　Addition to the Ease in Achieving ATS WCR of 200 Ka Because of their Current-Limiting Ability, Fuses Are Easy to Achieve Selective Coordination, Even Fault Currents.
