INDUSTRY TOPIC
Industrial and aerospace
Low-volume, high-value parts are the focus; since material options and mold designs vary, each project requires a dedicated review.

Short shots at the end, burnt weld lines, and surface marks all appear in the last-filled areas. This typically indicates inadequate venting.
Degradation-Induced Brittleness: Irreversible Damage from Extended Residence Time
Products show darkened colors, significantly reduced mechanical properties, and increased brittleness. Switching machines resolves the issue for the same material grade, indicating degradation-induced brittleness caused by prolonged residence time.
Flow Marks: Ripples from Cooling Flow Fronts
Concentric ripples appear on the product surface, typically in mid-to-rear sections or opposite the gate, creating a tactile unevenness. This defect is identified as flow marks.
Jetting Marks: Why the Initial Flow is Serpentine
Serpentine or earthworm-like patterns near the gate that fade away from the entry point, caused by jetting as the material enters the cavity.
LCP Industrial Connectors: Reliability, Gate Carbon, and Changeover
Industrial connectors must remain reliable despite temperature swings, vibration, oil exposure, and long service life. LCP meets these demands, but high-mix, low-to-mid-volume production introduces challenges in gate carbon buildup, material changeovers, and maintenance.
