SOURCES Mold Machine Material Process Design of gate too small or in wrong location Insufficient venting Machine not providing requested velocity Thermocouple pinched Heater overriding Wet material Viscosity too low Injection velocity too high Melt temperature too high or low Mold too cold RECOMMENDED ADJUSTMENTS Increase gate size Remove sharp corners from gate detail Change gate type Change gate location Insure proper venting Dry material Reduce injection velocity Increase melt temperature Decrease melt temperature Increase mold temperature Reduce mold temperature 28 Gravi-Tech SOURCES Mold Machine Material Process Hot runner system Gate design Screw configuration Heater malfunction Machine not providing requested velocity Contamination Wet material Injection speed too fast Residence time to high Too much decompression RECOMMENDED ADJUSTMENTS Insure proper venting Change flow pattern Change gate location Add venting to core pins Add ejector pins to gas traps Reduce clamp force Dry material Reduce compression Reduce melt temperature Reduce injection speed Increase transfer position Burns Root cause: Dieseling of trapped gas or material degradation through heat or shear. DEFECTS Design Guide 33 SOURCES Mold Machine Material Process Mold damages Loss of clamp force Barrel malfunction Contamination Wet material Melt temperature too high Injection speed too high Transfer position too low Excessive pack pressure Excessive back pressure RECOMMENDED ADJUSTMENTS Repair mold damage Clean parting line Reduce pinch-off land Increase clamp force Dry material Reduce melt temperature Reduce mold temperature Reduce injection speed Reduce hold pressure Increase transfer position Flash • Excess material commonly found at parting lines or mold features Root cause: Too much plastic or mold damage. 34 Gravi-Tech SOURCES Mold Machine Material Process Design of gate too small or in wrong location Machine not providing requested velocity Heater overriding Wet material Viscosity too low Injection velocity too high Melt temperature too high Mold too cold RECOMMENDED ADJUSTMENTS Increase gate size Remove sharp corners from gate detail Change gate type Move gate to a position where the melt stream will impinge upon a mold feature Dry material Reduce injection velocity Increase melt temperature Jetting Root cause: Injection speed is too high for the viscosity of the material DEFECTS Design Guide 35 SOURCES Mold Machine Material Process Finish too rough Venting impaired Screw configuration Overworking material Non-compatible additive Melt temperature too high Back pressure too high Injection speed too fast Mold too cold RECOMMENDED ADJUSTMENTS Remove sharp corners from gate detail Insure proper venting Increase gate size Use smaller screw/barrel Check melt uniformity Check L/D ratio Dry material Check additive compatibility Reduce melt temperature Reduce screw speed Reduce back pressure Reduce residence time Reduce injection speed Plate-Out • Build-up or deposit on mold surface Root cause: One component of the material is not totally compatible. 36 Gravi-Tech SOURCES Mold Machine Material Process Venting impaired Shut-off partially turned Screw problems Barrel heater problems New lot Contamination Material too dry Under-packing Injection speed too low Not enough pack pressure Melt temperature too low Transfer position too high RECOMMENDED ADJUSTMENTS Make sure gate is not blocked Insure runner shut-off is not turned Check venting Increase gate size Change gating location Add flow leader Insure cushion position Make sure screw is trans- ferring at a correct position Change screw/barrel Make sure material was dried at proper settings Increase melt temperature Increase mold temperature Increase injection speed Decrease transfer position Short Shot • Not enough material is being injected into the mold to fill out all of the cavities Root cause: Not enough plastic is getting into the cavity. Note: Once the process has been established, the parts should be tested for dimensional stability over the range of service termperatures.

For spiral flow information about a specific grade or additional details about the spiral flow test procedure, please refer to the TPE Tip #7. Further improvement can be obtained by positioning the valve recessed below the part surface or concealing the gate in the part detail for aesthetic products.

I am confident we will continue to provide our customers innovative solutions and world class service in support of their success and our growth in 2017 and beyond." is a premier provider of specialized polymer materials, services and solutions. 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 realize anticipated savings and operational benefits from the realignment of assets, including the closure of manufacturing facilities; the timing of closings and shifts of production to new facilities related to asset realignments and any unforeseen loss of customers and/or disruptions of service or quality caused by such closings and/or production shifts; separation and severance amounts that differ from original estimates; amounts for non-cash charges related to asset write-offs and accelerated depreciation realignments of property, plant and equipment, that differ from original estimates; our ability to identify and evaluate acquisition targets and consummate acquisitions; the ability to successfully integrate acquired businesses into our operations, such as Comptek, SilCoTec, Gordon Composites and Polystrand, including whether such businesses will be accretive, retain the management teams of acquired businesses, and retain relationships with customers of acquired businesses; 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 financial condition of our customers, including the ability of customers (especially those that may be highly leveraged and those with inadequate liquidity) to maintain their credit availability; the speed and extent of an economic recovery, including the recovery of the housing market; our ability to achieve new business gains; 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 the disposal of plastic 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 achieve or delays in achieving or achievement of less than the anticipated financial benefit from initiatives related to working capital reductions, cost reductions and employee productivity goals; an inability to raise or sustain prices for products or services; an inability to maintain appropriate relations with unions and employees; our ability to continue to pay cash dividends; the amount and timing of repurchases of our common shares, if any; 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.
