濟(jì)南注塑模具小批量生產(chǎn)中，由于是色粉與色母配色成型，造成色澤不勻，造成報(bào)費(fèi)嚴(yán)重。如果是大批量生產(chǎn)的話，采用抽粒料的話，就不存在色差問(wèn)題了。此外還有多個(gè)現(xiàn)象出現(xiàn)，要避免才行，下面來(lái)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(wěn)定
Dimensional instability
主要由于模具強(qiáng)度不良，精度不良，注射機(jī)工作不穩(wěn)定及成形條件不穩(wěn)定等原因，使塑件尺寸變化不穩(wěn)定。主要原因是人工取件的情況下，造成每模的成型周期不一致，導(dǎo)致產(chǎn)品尺寸也不穩(wěn)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
由于融料內(nèi)充氣過(guò)多或排氣不良而導(dǎo)致塑件內(nèi)殘留氣體，并呈體積較小或成串的空穴(注意應(yīng)與真空泡區(qū)別)。主要是量產(chǎn)中，由于料粉將排氣槽堵住，造成排氣不夠，產(chǎn)品內(nèi)部或局部就會(huì)產(chǎn)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(guò)大
Excessive flash
由于合模不良，間隙過(guò)大，塑料流動(dòng)性太好，加料過(guò)多使塑件沿邊緣擠出多余薄片。
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
由于融料分流匯合時(shí)料溫低，樹(shù)脂與附合物不相溶等原因，使融料在匯合時(shí)，熔接不良，沿塑件表面或內(nèi)部產(chǎn)生明顯的細(xì)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
由于融料沿模具表面不是整齊流動(dòng)填充型腔而是成半固化波動(dòng)狀在型腔面流動(dòng)或融料有滯流現(xiàn)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
由于填充作用過(guò)強(qiáng)，模具脫模性能不良等原因，使塑件脫模困難或脫模后塑件變形、破裂，或塑件殘留方向不符合設(shè)計(jì)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.520che.com.cn Look!
