Winning its ISO 13845 Medical Device Certification wasn’t easy for this custom molder, but it’s paying off for the company in many ways, including increased business.
ABA-PGT Inc., a fully integrated producer of precision tooling and high-volume, tight-tolerance plastic gears and other technical molded parts, recently received its ISO 13485:2003 Medical Device Certificate.
While ABA-PGT is not solely dedicated to the medical device industry, Terry R. Holmes, VP sales and marketing, said the medical device certification adds another level of credibility and value to the company’s capabilities.
“The majority of our business is to produce the tooling and provide the molding technology for plastic gears, which is our core area of expertise,” said Holmes in a telephone interview. “For several years, however, we’ve been doing non-gear precision parts in the medical device market that often lend themselves to the expertise we’ve developed in small, precision gear parts. That’s how we entered into the medical device field—through our high level of precision.”
ABA-PGT, headquartered in Manchester, CT, is a diverse custom molder that, in addition to gears and medical, provides components for the automotive, water management, HVAC, and business machine/paper path market segments. Currently the company operates with 52 molding presses ranging in size from 17-110 tons, and employs approximately 100. Holmes said that the company is looking to expand its tonnage range going forward.
Obtaining its ISO 13485:2003 Medical Device Certification gives the company a competitive edge when approaching companies in the medical device industry, Holmes explained. “I think the greatest benefit to having the medical certification is so that additional medical device companies will feel more comfortable working with us,” Holmes stated.
In addition to the ISO 13485:2003, ABA-PGT has its ISO 9001:2008 certification and is also in the process of becoming certified to the TS automotive standard as well. “Certification ensures ABA-PGT’s continued adherence to customer specifications and regulatory requirements,” added Holmes. —Clare Goldsberry
Plastic mold injection
Plastic mold injection involves heating and high-pressure injection of a thermoplastic into a water-cooled mold. A thermoplastic contains properties that allow it to soften when heated and harden again when cooled. Polystyrene, a rigid material used by AMT to mold model kit parts, is one such plastic. The mold injection process applied to producing model kits has several advantages over other methods. The thermally durable qualities of the polystyrene and quick-cooling manner of the injection technique make it extremely time- efficient. The time required to complete one mold, or "shot," can be measured in mere seconds. The curing time for the thermosetting method employed by many resin kit manufacturers can span minutes if heat cured, or hours if cold cured. The time-consuming nature of the cold method makes it ill-suited to a it manufacturer who needs to produce large quantities of plastic parts over a relatively short time span.

The design flaws, such as:
The design flaws, such as: poor location of the gate, the gate is too small, multi-gate parts runner arranged asymmetry, small flow, mold cooling system is unreasonable to make too much difference in mold temperature, etc. caused by melt flow in the mold cavity is not continuous, blocked air passage. lack the necessary mold parting surface of the exhaust or exhaust channel pore lack of congestion, poor location, and no inserts, ejector exhaust like the processing of the gap, resulting cavity in the air can not enter the time in the plastic At the same time to leave. The difference between the mold surface roughness, friction large, resulting in local hot spots, so that by the plastic decomposition.

This is a common problem, but also relatively easy to solve. When using technical means do not resolve, it can be considered from the mold design and manufacturing improvements, the general can be solved.
