濟南注塑模具小批（pī）量生產（chǎn）中，由於是色粉與（yǔ）色母配（pèi）色（sè）成型，造成色澤不勻（yún），造成報費嚴重。如果是大批量生產的話，采用抽粒料的話，就不存在色差問題了（le）。此外還有多個現象出現，要避免才行，下麵（miàn）來講講（jiǎng）吧（ba）。
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（liáng），精度不良，注射機工作（zuò）不穩定及成形（xíng）條（tiáo）件不穩定等（děng）原因（yīn），使塑件尺寸（cùn）變化不穩（wěn）定。主要（yào）原因是人工取件的情（qíng）況下，造成每模（mó）的成型周期不一致，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（pái）氣不良而導致塑件內殘留氣體，並（bìng）呈體積較小（xiǎo）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（gòu），產品內部或局部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，塑料流動性太好，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（yóu）於融料分流匯合（hé）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，沿塑件表麵或內部產（chǎn）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.
塑件表麵波紋
Surface ripple of plastic parts
由於融料沿模具表麵不是整齊流動填充型（xíng）腔而是成半固化波動狀在型腔麵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（liáng）
Die Adhesion
由（yóu）於填充作用過強，模具脫模性能不良等原因，使塑件脫模困難或脫模後塑件變形（xíng）、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.
To avoid these phenomena during mass production of injection molds, that's it. If you have any questions about this, please come to our website http://www.lsjtcyjt.cn Look!
