根據模流分析,這裡是最佳進澆位置.This is the best gate location according to flow simulation.我們建議使用潛伏膠口.We suggest submarine gate.

澆口型式: 一個側膠口及一個扇型澆口Gate type : One side gate and one fan gate

如果不接受潛入式膠口,建議改用側膠口.If submarine gate is not accepted, we suggest side gate.

如果用冷流道設計時,豎澆道太長了,約有200mm長.The sprue will be too long if we use cold runner design. Its length is around 200 millimeters.

冷流道系統流動不均, 推薦使用熱膠道以使流動較佳Flow imbalance by cold runner. We recommend a hot runner system for better flow.

如果澆口在這裡,成品脆弱處會有會膠線.有必要更改進膠的位置.There will be welding line at part weakness area if the gate locate here. It is necessary to change the gate location.

會膠線將於此處，須製作排氣入子或形梢

以排氣。

Welding line will be here. Suggest to make venting insert or core pin for venting.在敞開處增加一個跨橋以增加流動Add a cross bridge through open area to increase flow.

澆口太小了,無法完全充填.The gate is too small for complete filling.

成品有短射,我們應該要加大澆口尺寸.並增加排氣槽.There is part short shot. We should enlarge the gate dimension and add venting slot.

小點進膠處需二次剪膠Degating after molding is required due to pin gate design.需二次剪膠加工Secondary process for degating is required.

需二次剪膠加工,建議容許銑膠深度0.1MM,避免影響組裝Secondary process for degating is required. Suggest to allow 0.1 mm depth for degating in order to avoid assembly interference.

進膠點逃 0.3mm的小凹避免殘料击出成品

面.

Make a dimple in 0.3 mm depth to prevent flash protrude over part surface plane.進膠點增肉0.3mm方便塑膠流動.Make a dome in 0.3 mm height to increase flow ability.

須要二次後加工切除料頭,我們會盡量切平整,但是可能還會有殘料的風險.Degating after molding is required. We will try to cut it as flat as possible but still with the risk of remnant.

避免剪膠殘料干涉組裝.建議做凹槽.Suggest a recess to prevent assembly interference caused by degating remnant.

此處需二次剪膠,所以建議"底座"相對位置作圓孔,以避免干涉。Secondary process for degating is required. Suggest a dimple at the related position on "base" to avoid assembly interference.

建議進膠點往上移,避免鐵件拉傷Suggest to move the gate location upper to avoid stamping part scratch.

建議成品進膠處做凹槽以利剪膠後殘料不會溢出。Suggest to make a recess at the gate location to prevent degating remnant exceed the plane.

我們將會用冲壓治具來進行剪膠.We will use press jig for degating.

我們將會用銑床來進行剪膠.We will use milling for degating.

我們將以人工剪除澆口.We will cut the gate manually.

剪膠後殘料在 0.3 mm 以內The remnant after degating is within 0.3 mm.

建議成品進膠處做凹槽以利剪膠後殘料不會溢出。Suggest to make a recess (8.0*0.5) at the gate location to prevent degating remnant exceed the plane.

在 clip 處改用側膠口以取代潛入式膠口(靠

近日期章處)

Remove sub gate and replaced by side gate at clip (near the date code )

預留第二個 clip當作進澆處,一但發生縮水

時便可使用

Reserve another clip once a shrinkage issue is occurred.

Gate處建議成品減肉0.3MM(如上圖所

示)，避免殘料击出成品。

Suggest to reduce 0.3mm part thickness at gate area to avoid remnant protrusion.下载本文
