Proper part design and plastic molding processes are important to avoid deformed conditions such as sink marks, warping, shrinking, flashing (excess material) and knit lines. Orders for plastic injection molding often receive the following engineering services and reviews:

•   Advise on the degree of draft to facilitate the ejection/removal process.

•   Provide recommendations on wall thickness, ribs and bosses to ensure part strength and cosmetic appearance.

•   Design of over-molds, insert molding, hinges and snaps for function and structure.

•   Select plastic materials based on part volume and tolerance requirements.

•   Design gates and runners to ensure consistent flow, correct pressure and sufficient material to minimize deformation, flashing, sink marks and knit lines.

•   Review of our wide range of surface finishing options.

•   Review all design, material and application considerations to ensure low costs and the best value.

•   In-house 3D printing services for design validation and evaluation.
