Processing
Pre-drying of Pellets
GLAMIDE™ is shipped as a dried pellet packed in a moisture-proof bag. If the bag is unsealed pre-drying will be required.
We recommend using the pellets immediately after unsealing the bags. If the pellets are left as is they will absorb moisturefrom the air. Accordingly please avoid exposing pellets to the air for a long time. A general guideline for drying pellets thathave absorbed moisture: Dry for 3-5 hours at 80-120°C taking care not to over dry the pellets which may cause discoloration
due to oxidation.

Mold Design(1) Selecting the Tool Material
In general, polyamides reinforced with glass fiber or other fillers cause more abrasion to a mold than non-reinforced polyamides during molding.
For that reason, we advise that you adhere to the following guidelines when making the tool. As damage around the gate area can be particularlysevere, we strongly recommend using the following materials for at least that region of the tool.
1. Use tool steel alloys such as SK, SKS, or SKD treated with hardening and tempering agents to reach HRC55 to 60.
2. Use pre-hardened steel or precipitation hardened steel.
3. Use one of the following surface hardening treatments.
• Rigid chrome plating treatment• Nitriding treatment• Cermet treatment(2) Gate
When designing gates, minimizing damage to the glass fiber in filled resin should be carefully considered. As the viscosity of GF-reinforced
polyamide is higher than that of non-reinforced material, it is important to ensure a well-rounded corner at the junction between a runner and agate to reduce flow resistance.
Additionally, optimal gate placement should be considered given that the position of the gate can affect weld lines, causing undesirable
appearance, decreased strength, and/or warpage. As a general guideline for the dimensions of a side gate, please use a thickness of around 60%of the molded part wall thickness, a width 1.5-3 times as wide as the gate thickness, and a land length of about 50% of the gate thickness. For apin gate, a gate diameter of 0.8-1.5mm can be used as a general guideline.

(3) Venting
Reinforced polyamide tends to generate more gas than non-reinforced polyamides. Please ensure good mold ventilation by fitting with air vents
about 50μm deep in areas where resin flow converges.

SafetyMolding Operation• When purged resin contains a large quantity of gas or steam, the resin may have been insufficiently dried. We recommend re-drying the resin.
• Resin held in the cylinder for an extended period of time may lose viscosity or experience other impacts on quality. Please resume molding only
after
thoroughly replacing the resin that has been held too long in the cylinder with new resin.
• When switching from GLAMIDE™ to another polymer, replace the GLAMIDE™ with polyethylene or polypropylene to purge. Local and general
ventilation arerecommended.
• Keep hands and face away from the nozzle during molding to prevent burn injury.
• Please ensure proper ventilation, as a small amount of gas and fine dust may be produced during molding.

Protective equipment• Wear appropriate protective equipment such as protective clothing, safety glasses, and gloves to protect eyes and skin from the molten resin.

Emergency Response• Should molten resin adhere to the skin, cool the area immediately with cold water or an ice pack and then seek medical attention. Do not
attempt to peel
the resin off of the skin.

Other• Do not let molten resin touch electric wires or hoses.
• Molten resin reaches high temperatures and can catch fire if it forms large clumps when purging. Break up large clumps and allow to cool before
disposal.
• Spilled pellets can be a slipping hazard, so be sure to clean them off the floor immediately.
