Plastic injection molding

Expect more from your mold flow analyses

Two of the major objectives a molder has entering a project are to preserve the material properties the customer is seeking and to produce a part to print. Mold flow analysis (MFA) is a critical tool for designing successful parts and tools for plastic injection molding. But it’s only as good as the expertise of the team conducting it, and their ability to interpret the data it generates.

A well-designed and analyzed MFA can help you build tooling that consistently produces high-quality parts a

Beyond PPAP: How NBP streamlines the project launch process

While the Production Part Approval Process (PPAP) is a common method injection molders use to ensure a new part meets expectations, New Berlin Plastics takes additional steps to streamline the entire project launch process.

These extra steps provide efficiencies that often result in parts being approved and moved into production faster, saving time and cost for OEMs.

“We take these exhaustive process verification and validation steps to give OEMs a robust production process that is both in con

New plasma atomization reactor enables The Virtual Foundry to expand its range of exotic metals

As part of The Virtual Foundry’s continuing efforts to help its customers develop unique materials with exceptional physical properties for additive manufacturing, the advanced material science company has acquired a plasma atomization reactor.

This device uses plasma to melt and atomize metal, creating small, uniform, dense and spherical metal powders that are ideal for additive manufacturing. The Virtual Foundry uses them to create plastic impregnated filament via its patented process, which

How a design review can help you avoid part quality problems

Conducting a design review early in your part design process is a critical step to avoid manufacturing and quality problems later.

What is a design review? A comprehensive analysis of your part and tooling design to optimize them for manufacturability. It also involves deciding on the most cost-effective material and process to produce your parts.

Why do you need to do a design review? Because your part and tool designs may contain features that could significantly add to the cost of your part

Adding value upfront with DFM

For many types of engineered products, the sooner you can discover and solve design and manufacturability problems, the better. Nowhere is this more true than in plastic injection molding. High-quality molded parts require a perfect synergy between part design, mold design, and molding processes.

That’s why New Berlin Plastics conducts a preliminary design for manufacturability (DFM) analysis during the part quoting process. Its purpose is to obtain an overview of the design intent, the applica
