MOLD DESIGN RECOMMENDATIONS
Gates
• Many different types of gates can be used such as pin, fan, tunnel, tab and edge gates.
Cut vent depths to:
- PPA Compounds: 0.0015"–0.0025" depth and 0.250" width
- PC Compounds: 0.002"–0.004" depth and 0.250" width
- PSU Compounds: 0.003"–0.004" depth and 0.250" width
- PES Compounds: 0.003"–0.004" depth and 0.250" width
- PPS Compounds: 0.002"–0.003" depth and 0.250" width
- Acetal Compounds: 0.0015" minimum depth and 0.250" width
- PEEK Compounds: 0.002"–0.004" depth and 0.250" width
- Nylon Compounds: 0.002" minimum depth and 0.250" width
• Increase vent depth to 0.060" (1.5mm) at 0.250" (4.0mm) away from the cavity
and vent to atmosphere.

They are based on management's expectations that involve a number of business risks and uncertainties, any of which could cause actual results to differ materially from those expressed in or implied by the forward-looking statements.
Factors that could cause actual results to differ materially from those implied by these forward-looking statements include, but are not limited to: our ability to identify and evaluate acquisition targets and consummate and integrate acquisitions; disruptions, uncertainty or volatility in the credit markets that could adversely impact the availability of credit already arranged and the availability and cost of credit in the future; the effect on foreign operations of currency fluctuations, tariffs and other political, economic and regulatory risks; changes in polymer consumption growth rates and laws and regulations regarding plastics in jurisdictions where we conduct business; changes in global industry capacity or in the rate at which anticipated changes in industry capacity come online; fluctuations in raw material prices, quality and supply, and in energy prices and supply; production outages or material costs associated with scheduled or unscheduled maintenance programs; unanticipated developments that could occur with respect to contingencies such as litigation and environmental matters; an inability to raise or sustain prices for products or services; an ability to achieve or delays in achieving or achievement of less than the anticipated financial benefit from initiatives related to acquisitions and integration, working capital reductions, cost reductions and employee productivity goals; information systems failures and cyberattacks; and other factors affecting our business beyond our control, including, without limitation, changes in the general economy, changes in interest rates and changes in the rate of inflation.

Another color-related challenge is the multitude of different color streams of
recycled PET, which can limit the uses for recycled colored PET.
This predictive technology maximizes
the use of different color streams and reduces waste.
Manufacturers using rPET require different properties based on their specific
application, such as certain colors, stiffness and strength.
