In the consumer electronics industry, the product enclosure not only provides structural strength and heat dissipation but also serves as a key expression of brand aesthetics. Achieving high-quality appearance while ensuring stable, high-volume production remains a core challenge in mold…

At RiLong, we don’t just mold silicone. We overmold it onto metal inserts — often for customers who have already been burned by delamination, shifting inserts, or invisible rejects. Below are five practical lessons we’ve learned the hard way. If…

In plastic injection molding, the initial tooling cost is always a hot topic. I often hear: “Can we find a cheaper mold?” But after years in this industry, I’ve learned one hard truth: Mold price is what you pay upfront;…

Drawing from years of project experience, We’ve summarized the following cost-reduction strategies from four dimensions: production efficiency, part design, material standardization, and maintenance optimization. We hope these insights prove valuable to industry peers. Strategy 1: Mold Structure & Production Efficiency…

Injection molding brings your product to life—but surface finishing gives it soul. For plastic parts, the real differentiator between “ordinary” and “premium” often lies in the post-molding treatment. The same ABS or PC material can feel like metal, ceramic, or…

Incorporating multi-material designs (e.g., rigid plastic + soft TPE) into products not only enhances grip comfort but also adds functionalities such as waterproofing and shock absorption. However, choosing between Two-Shot Molding and Overmolding is often the first major challenge engineers…

Optimizing Gate Design to Avoid Sink Marks (Dents) in Injection Molding The core principle behind optimizing gate design to prevent sink marks is to ensure that the molten material can effectively pack out the thick-walled areas during the holding pressure…
