プラスチックの設計およびエンジニアリングプロジェクトを開始するとき, 目標は、高品質の射出成形コンポーネントを作成および製造することです. それを達成するために, 実際の製造プロセスがスムーズに機能するように、設計およびエンジニアリングプロセスのいくつかの重要な部分をフロントエンドで検討することをお勧めします。. これにより、最終的には時間とお金を節約できます。.
- 適切な素材を選択する
これは、前の 4 つのルールの中で最も単純なルールかもしれません。. 部品に適した材料を決定する. Is this a medical part? An automotive part? What are the requirements? Does it need to be flexible or rigid? Does the part need to withstand extreme cold or hot temperature? What material do other similar parts use? These questions are just the beginning. Thoroughly research which material works the best for the specific part you’re looking to produce.
- Make Sure The Wall Thickness Is Uniform
Making sure that the wall thickness of your part are as uniform as possible to avoid warpage, ヒケ, voids, flow restrictions and longer, uneven cooling times. If uneven wall thickness is essential to the part, try to strive for smooth transitions that gradually taper.
- Try To Avoid Undercuts
Undercuts make it difficult to de-mold your part. The undercut piece of plastic will get lodged inside the mold once the part has hardened and cooled, making it difficult to eject the part from the mold. When undercuts are necessary to the part, and not a byproduct, many manufacturers have lifting mechanisms and side actions to help de-mold the part.
- Try To Avoid Sharp Corners
Try to avoid designing and engineering a part with sharp, squared edges. Sharp edges, like 90-degree angles, produce parts with molded-in stresses. The results are weak points within the part, which leads to cracking and/or part failure. If your part must have a sharp corner, adding a radius or several radiuses will reduce the higher levels of molded-in stress. The radius will redistribute the stress and allow the material to flow more evenly, thus avoiding breakage or failure.
- Make Sure To Consider Warpage And Shrinkage
Materials cool and shrink differently when your injection molded part cools. Warpage and shrinkage are both kinds of distortion that can happen during the cooling process. Warpage distorts the dimensions and is often caused by excess stress on the part itself. Shrinkage occurs when there’s a difference between the linear dimension of the molded part and the mold itself. In order to prevent one or the other, pay close attention to the tooling, part geometry and processing of the part.
