Working with Vectra A950
Is Vectra easy to machine?
Machinable with sharp carbide/PCD tools and high speed, low feed, but the fibrillar skin tends to fuzz and delaminate at edges; avoid deep interrupted cuts and support thin webs.
Can Vectra be welded?
Solvent and ultrasonic welding are unreliable because of the anisotropic skin; use laser transmission welding, heat staking, insert molding or mechanical/adhesive joints (surface pretreatment required for bonding).
Can Vectra be formed, bent or molded?
Inject at 285–330 °C (E-series to ~350 °C) with 40–130 °C molds, small gates and very high injection speed; dry 4 h at 150 °C, place gates to steer flow because weld lines retain only ~20–40 % of flow-direction strength.
What surface finishes work on Vectra?
Molded surfaces reproduce the tool finish well; can be laser-marked, vacuum-metallized or (with LDS grades) laser-activated and electrolessly copper/nickel/gold plated — painting needs plasma or primer pretreatment.

Vectra A950 — frequently asked
What is Vectra A950 used for?
Vectra A950 is typically used for SMT connectors, camera module housings, micro-precision gears and RF/antenna components. In short: industry reference LCP resin; high-flow thin-wall molding; LDS-platable grades available.
What is the tensile strength of Vectra A950?
Vectra A950 has a typical tensile strength of 182 MPa (26.4 ksi) — stronger than 98% of polymer grades. Strength varies by condition: see the 10 listed tempers.
Is Vectra A950 easy to machine?
Reasonably — machinability is rated good (55/100, worse than 64% of polymer grades). Machinable with sharp carbide/PCD tools and high speed, low feed, but the fibrillar skin tends to fuzz and delaminate at edges; avoid deep interrupted cuts and support thin webs.
Can Vectra A950 be welded?
Not readily — weldability is rated poor (25/100). Solvent and ultrasonic welding are unreliable because of the anisotropic skin; use laser transmission welding, heat staking, insert molding or mechanical/adhesive joints (surface pretreatment required for bonding).
What surface finishes work on Vectra A950?
Molded surfaces reproduce the tool finish well; can be laser-marked, vacuum-metallized or (with LDS grades) laser-activated and electrolessly copper/nickel/gold plated — painting needs plasma or primer pretreatment.
Can Vectra A950 be formed, bent or molded?
Inject at 285–330 °C (E-series to ~350 °C) with 40–130 °C molds, small gates and very high injection speed; dry 4 h at 150 °C, place gates to steer flow because weld lines retain only ~20–40 % of flow-direction strength.
What is the maximum service temperature of Vectra A950?
Vectra A950 is rated for continuous use to about 200°C (392 °F), and briefly to 280°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
