Points to consider when designing plastic products

Points to consider when designing plastic products

"How steep should the slope be?" and "Is it necessary to install ribs?" Here are the key points!

Here are some points to consider when designing a product. Starting with "Where should the parting line (PL/top, bottom, left, right separation line) be placed?", there are also considerations such as "What should the draft angle be?" and "Is it necessary to install ribs?" Additionally, it is important to minimize undercuts (such as side holes or recesses) that could cause interference with the opening and closing direction of the mold. 【Key Points for Product Design (Excerpt)】 ■ Where should the parting line (PL/top, bottom, left, right separation line) be placed? ■ What should the draft angle be? (To facilitate removal from the mold) ■ What is the wall thickness of the main wall? (To ensure strength and rigidity) ⇔ Risk of sink marks and extended cycle time ■ Is it necessary to install ribs? (To provide reinforcement and rigidity) ⇔ The relationship with the main wall is important *For more details, please refer to the PDF document or feel free to contact us.

Our proprietary "IMM Method"

Our proprietary "IMM Method"

Eliminate insufficient strength from the ground up and achieve highly reliable plastic and resin parts!

The "IMM method" was completed in 2011 as a technology to solve the strength deficiency of weld lines in fiber-reinforced resin materials. This technology is considered a part of injection compression technology, characterized by its ability to indirectly apply compression and internal flow in areas where compression is needed. The very high compression force generates a strong holding pressure effect, allowing for intentional changes in the internal flow of the resin during injection. The compression effect suppresses shrinkage and produces high dimensional accuracy. The internal flow promotion effect improves the strength of the weld lines in fiber-reinforced resins and allows for control of fiber orientation. In particular, the IMM method can achieve high precision control through its uniquely developed machinery, independent of the injection process, resulting in no variation between shots and stable effects. It is possible to accommodate this method by modifying existing molds. 【Features】 ■ Measures for dimensional accuracy, shrinkage, and deformation of thick and uneven products ■ Improvement of weld line strength and control of fiber orientation ■ Flexibility in product shapes that can be accommodated, such as slide block structures
