Q

PA6 Weld Line Strength

A

The PA6 weld line is a required question of structural design; position transfer takes priority over process remedy, and load-bearing areas must stay away from weld lines; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Q

PA66 glass fiber reinforced warpage

A

Glass fiber PA66 warpage originates from orientation anisotropy; gate design, uniform-temperature cooling, and straightening fixtures constitute a complete warpage reduction solution; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence

Q

PA66 wall thickness design specifications

A

PA66 wall thickness design has a clear window; uniform wall thickness plus gentle transition is the fundamental means to resolve short shots and sink marks simultaneously from the structural end; after confirming effectiveness, fix the parameters and practices into the work instructions to preven...

Q

PA66 shrinkage rate 1.5-2%

A

PA66 shrinkage rate ranks first among nylons; mold allowance reservation, wall thickness uniformization, and holding pressure compensation are the three axes of dimensional control; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence

Q

PA66 power tool housings

A

Tool housings require rigidity-toughness balance and thermal management system design; material modification, structural heat dissipation, and joint verification constitute a complete solution; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent ...

Q

PA6 Warpage

A

PA6 warpage = 'high shrinkage + orientation': setting fixtures are a sharp tool; warpage of crystalline materials requires balancing mold temperature, restraining holding pressure, and constraining setting in three ways, and the setting constraint after demolding is especially effective.

Q

PA12 SLS Laser Parameter Matching

A

SLS laser parameters depend on the comprehensive value of energy density, and raising power alone easily causes overburning; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a referenc...

Q

PA12 SLS Powder Bed Preheating Temperature

A

170-180℃ powder bed is the core of the SLS window, and bed surface temperature difference must be monitored by thermal imaging; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Q

PA12 Shrinkage Depression and Wall Thickness Upper Limit

A

For thick-wall depressions, first reduce material; the 7-10mm wall thickness upper limit is a design red line; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubles...

Q

PA12 Long-flow Thin-wall Part Temperature Strategy

A

Long-flow thin-wall parts can use the 300℃ upper limit in exchange for flow, and the residence time must be shortened simultaneously; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
