Ejector pin vents are self-cleaning, but they should be wiped once a day to remove build-up.

Our end markets include consumer, packaging, healthcare, industrial, transportation, building and construction, telecommunications and energy. Our colorant and additives concentrates are used in a broad range of polymers, including those used in medical and pharmaceutical devices, food packaging, personal care and cosmetics, transportation, building products, wire and cable markets. Our liquid polymer coatings and additives are largely based on vinyl and are used in a variety of markets, including consumer, packaging, healthcare, industrial, transportation, building and construction, wire and cable, textiles and appliances.

They apply to, among other things, electrical appliances, power electronics, smart buildings and grid infrastructure, electronic/electrical connectors and Electric Vehicle charging infrastructure.

Building on the positive start to the year, we delivered a strong second quarter, highlighted by broad-based growth across all regions and most end markets,” said Dr.

Design Guide 33 Mold damages Loss of clamp force Barrel malfunction Melt temperature Injection speed Transfer position Excessive pack Excessive back Repair mold damage Clean parting line Reduce pinch-off land Increase clamp force Dry material Reduce melt Reduce mold Reduce hold pressure Increase transfer Flash • Excess material commonly found at parting lines or mold features Root cause: Too much plastic or mold damage. 34 Gravi-Tech Design of gate too small or in wrong location Machine not providing Heater overriding Viscosity too low Injection velocity too high Melt temperature Remove sharp corners from Change gate type Move gate to a position where the melt stream will impinge upon a mold feature Dry material Reduce injection Increase melt Jetting Root cause: Injection speed is too high for the viscosity of the material Design Guide 35 Finish too rough Screw configuration Overworking material Non-compatible additive Melt temperature too high Remove sharp corners from Use smaller screw/barrel Check melt uniformity Check L/D ratio Check additive compatibility Reduce melt Reduce screw speed Reduce residence time Plate-Out • Build-up or deposit on mold surface Root cause: One component of the material is not totally compatible. 36 Gravi-Tech Shut-off partially turned Screw problems Barrel heater problems Material too dry Under-packing Not enough pack Melt temperature Transfer position Make sure gate is not blocked Insure runner shut-off is not turned Check venting Change gating location Add flow leader Insure cushion position Make sure screw is transfer- ring at a correct Change screw/barrel Make sure material was dried at proper settings Increase melt Increase mold Decrease transfer 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. A reciprocating screw rotates to build a shot. This compression ratio is what helps build the shot size at the front of the screw.

Fiber-Line had the best quarter in its history as a result of the continued build-out of 4G and emerging 5G network infrastructure.
