In injection molding, one of the most common—and most debated—decisions is how many cavities a mold should have. But when you're producing two different parts that belong to the same assembled product, the choice often narrows down to two options:
Option A: Two separate single-cavity molds (one for Part A, one for Part B).
Option B: One family mold with a 1+1 cavity configuration (both parts in the same tool).
At first glance, Option A seems simpler. But for many applications, Option B is the superior choice—and here's why.
In the world of plastic injection molding, the mold is often called the "money printer." Feed it plastic pellets, apply heat and pressure, and out pop the parts that make modern life possible—automotive components, medical devices, consumer electronics, and everyday household items.

Today, we’ll walk through the complete production workflow for our two-piece premium NFC card holder, focusing on the star craft—holographic foil stamping on embossed clear polycarbonate (PC) injection-molded back plates. We will also clarify how the mold embossed logo, NTAG424 DNA NFC sticker integration, PVC cover assembly and UV resin sealing work together as a full production line.
If you’re a product designer, brand manager or sourcing engineer looking to upgrade your plastic card accessories with high-end anti-counterfeit visual effects, this step-by-step guide will answer all your technical doubts.
Have you ever picked up a plastic hanger and noticed how surprisingly sturdy yet lightweight it feels? Or wondered why some hangers have perfectly smooth surfaces while others show unsightly dents and sink marks? The answer often lies in a sophisticated manufacturing technique called Gas-Assisted Injection Molding (GAIM).
This article provides a comprehensive analysis of the GAIM process for plastic hanger production, covering everything from basic principles to advanced tooling considerations, including the critical choice between hot runner and cold runner systems.
Sustainability is no longer a marketing add-on — it is a manufacturing imperative. Brand owners, OEMs, and molders are under increasing pressure to incorporate recycled content into their products. At the same time, hot runner systems have become the industry standard for high-volume, high-quality injection molding.
READ MOREWhile procurement and management focus on cost and compliance, the real battle with recycled material happens on the shop floor—and at the CAD terminal. For mold designers, toolmakers, and process engineers, recycled content isn‘t just a material specification change. It fundamentally alters how you design the mold, what steel you choose, how you cool it, and how you run it.
Here’s what the injection molding industry needs to know about recycled material—from the mold design phase all the way to production.
