注塑模具在量產時要避免出現這些現象

來源☁•▩·│:http://www.voyagesvietnamcambodge.com/ 日期☁•▩·│:2022-08-27

濟南注塑模具小批次生產中•│☁,由於是色粉與色母配色成型•│☁,造成色澤不勻•│☁,造成報費嚴重╃·✘·•。如果是大批次生產的話•│☁,採用抽粒料的話•│☁,就不存在色差問題了╃·✘·•。此外還有多個現象出現•│☁,要避免才行•│☁,下面來講講吧╃·✘·•。
In the small batch production of injection molds in Jinan, due to the color matching and molding of toner and masterbatch, the color is uneven, resulting in serious fee reporting. If it is a mass production, there will be no color difference if the granular material is used. In addition, there are many phenomena that should be avoided. Let's talk about them.
尺寸不穩定
Dimensional instability
主要由於模具強度不良•│☁,精度不良•│☁,注射機工作不穩定及成形條件不穩定等原因•│☁,使塑件尺寸變化不穩定╃·✘·•。主要原因是人工取件的情況下•│☁,造成每模的成型週期不一致•│☁,導致產品尺寸也不穩定╃·✘·•。
It is mainly due to the poor strength and accuracy of the mold, the unstable operation of the injection machine and the unstable forming conditions, which make the size change of the plastic parts unstable. The main reason is that the molding cycle of each mold is inconsistent and the product size is unstable when the parts are taken manually.
氣泡
Bubble
由於融料內充氣過多或排氣不良而導致塑件內殘留氣體•│☁,並呈體積較小或成串的空穴(注意應與真空泡區別)╃·✘·•。主要是量產中•│☁,由於料粉將排氣槽堵住•│☁,造成排氣不夠•│☁,產品內部或區域性就會產生氣泡或燒焦╃·✘·•。
The residual gas in the plastic part is caused by excessive inflation or poor exhaust in the molten material, and is in the form of small volume or string of cavities (note that it should be distinguished from vacuum bubbles). The main reason is that in mass production, the exhaust slot is blocked by the material powder, resulting in insufficient exhaust, and bubbles or scorching will occur in the product or locally.

飛邊過大
Excessive flash
由於合模不良•│☁,間隙過大•│☁,塑膠流動性太好•│☁,加料過多使塑件沿邊緣擠出多餘薄片╃·✘·•。
Due to poor mold closing, too large gap, too good plastic fluidity, and too much feeding, the plastic parts extrude extra sheets along the edge.
熔接不良
Poor welding
由於融料分流匯合時料溫低•│☁,樹脂與附合物不相溶等原因•│☁,使融料在匯合時•│☁,熔接不良•│☁,沿塑件表面或內部產生明顯的細接縫線╃·✘·•。
Due to the low material temperature and the incompatibility between resin and attachments when the molten materials are separated and merged, the fusion of the molten materials is poor, and obvious fine seam lines are generated along the surface or inside of the plastic parts.
塑件表面波紋
Surface ripple of plastic parts
由於融料沿模具表面不是整齊流動填充型腔而是成半固化波動狀在型腔面流動或融料有滯流現象╃·✘·•。
Because the melt does not flow neatly along the mold surface to fill the cavity, but flows in a semi solidified wave shape on the cavity surface or the melt has stagnant flow.
脫模不良
Die Adhesion 
由於填充作用過強•│☁,模具脫模效能不良等原因•│☁,使塑件脫模困難或脫模後塑件變形·•✘╃☁、破裂•│☁,或塑件殘留方向不符合設計要求╃·✘·•。
Due to the strong filling effect and poor mold demoulding performance, it is difficult to demould the plastic parts, or the plastic parts are deformed and cracked after demoulding, or the residual direction of the plastic parts does not meet the design requirements.
