Якасныя пластыкавыя кампаненты
Калі вы выкарыстоўваеце вядомага вытворцы пластмас, гэта паказвае. На жаль, калі вы наймаеце нядобрасумленнага вытворцы, гэта паказвае больш. Пры найманні вытворцы, Пазбягаць дэфектаў вырабленых пластыкавых дэталяў варта ў першую чаргу. Вось некалькі саветаў, як пазбегнуць дэфектаў, для амаль бездакорнай вытворчасці.
Гэтыя тры фактары вызначаюць поспех або няўдачу вытворчага запуску:
- Апрацоўка
- Цвіль
- Матэрыял
Making sure each of these elements is functional before the molding process is key. This is why it’s important to partner with a plastics manufacturer you can trust. If you’ve worked with a disreputable or inexperienced manufacturer, you may have encountered these defects.
Common Processing-Related Defects:
Burn Marks – Improper ventilation or extended heating of the mold can cause unsightly black or brown carbon deposits.
Blistering – Too much heat or inadequate cooling causes bubbles or raised imperfections.
Stringing – Much like a hot glue gun, stringing happens when the nozzle is too hot and an excess strand of plastic attaches to the part.
Stress Cracking And Crazing – Exposure to high temperature for too long can cause the appearance of crackling or single cracks.
Cold Slugs – When an extra tab of hot plastic becomes attached to the part, it causes a non-uniform area.
Sink Marks And Voids – Poor part design, non-uniform heating and/or inadequate cooling can cause depressions or hollows in a part.
Flow Marks – When a part cools too quickly, it can cause a wavy pattern or discoloration in the part.
Common Mold Design And/Or Maintenance Defects:
Warping – When the cooling system works improperly, the mold can cool unevenly, causing warped, bowed effect.
Drag Marks – Improper or misaligned injector systems can cause scratches when the part is ejected from the mold.
Jetting – Incorrect gate size, length or placement can cause a snake-like line of plastic that cools at a different rate than the main part.
Short Shot – An injection blockage can cause the mold to be improperly filled, which creates an incomplete part, or a short shot.
Flash Or Burrs – If the mold is damaged, poorly designed or there is poor clamping force, a thin protrusion can form beyond the body of the part.
Defects Linked To The Materials:
Splay (Often Called “Silver Streaks”) – These are circular marks caused by excess moisture in the resin. They appear where the molten plastic hits the mold cavity.
Delamination – This is caused by moisture in the pellets. The result is a flaky, crumbly surface layer.
Color Streaks – This is just as the name suggests, random streaks of color in your part. This comes from poorly mixing resins and colorants, or non-uniform ingredients.
Contaminates Embedded In The Material – This is caused by flecks or particles foreign material that often originates in the barrel of the press.
Discoloration – This is caused by residual color in the hopper, usually due to improper flushing or not flushing the hopper at all.
