Industrial Metal-to-Plastic Conversion: 3 Case Studies

Several industrial sectors are converting metal components to plastic to gain efficiencies in cost, weight, performance, aesthetics, and durability. While these are compelling reasons to consider plastic versus metal, the process isn’t necessarily right for all industrial applications.

A comprehensive feasibility analysis can help you determine if your project is suitable for metal-to-plastic conversion by evaluating it from three fundamental perspectives: design, manufacturability, and return on investment.

How to Speed Up Cycle Time for Injection Molded Plastic Parts

Cycle time directly influences plastic part cost and capacities, so keeping it as low as possible is the overarching goal of engineers and project managers. When getting quotes from various injection molders for plastic parts, they may be confronted with divergent cycle time estimates, calling accuracy and the molder’s capabilities into question.

What is Design for Manufacturability in Injection Molding?

Generally speaking, Design for Manufacturability (DfM) — or Design for Manufacturing — is the process of consciously and proactively designing products to optimize all facets of manufacturing. 

DfM methodology aligns engineering and production in the design phase, ensuring cost and time efficiencies, superior quality, regulatory compliance, and end-user satisfaction. Problems are identified and addressed early in the product development process, preventing costly issues that could impact manufacturability: raw materials selection, tolerances, and secondary processing.

Plastic Injection Molding vs 3D Printing – Which is Better?

Among today’s manufacturers, both 3D printing and plastic injection molding are viable options for producing complex plastic parts and components. While originally considered competing technologies, these techniques are now each largely recognized as having  unique advantages and can even be used together to help optimize production efficiency.

What is Design of Experiments (DOE) in Scientific Molding?

Each new plastic injection molding project has three inherent goals: performance for the customer; production efficiency for the manufacturer; and, reliability for the end user.

These goals are reasonable. The challenge lies in accomplishing all three within a desired timeframe and budget.

To do so, injection molding plastics engineers turn to Design of Experiments (DOE) to identify flaws during the process design phase that might otherwise derail project success.

Injection Molding Design Tips to Get Defect-Free Products to Market Fast

When it comes to remaining competitive in the global marketplace, speed matters. Manufacturers want injection molded parts that deliver the most product functionality at the lowest cost — and they want the parts quickly to get to market first and fastest.

Injection molders understand the pressure manufacturers are under. They're also attuned to how injection molding design, engineering, and production expertise can greatly speed up development time.

How Draft Benefits Injection-Molded Part Design and Outcomes

Custom injection molding is a go-to for OEMs across a range of industries because of design and engineering precision, production repeatability, and cost-effective solutions. 

Injection molders understand that consistently delivering defect-free parts and products to these standards is a top priority and a true value-add to their OEM partnerships.

Quality assurance begins in the design phase. Engineers are faced with many decisions, but among the most important are those that impact the end of the injection molding process — what has to happen to ensure the plastic part ejects cleanly?

GD&T: A Practical Approach for Injection Molded Parts

Geometric dimensioning and tolerancing (GD&T) is a symbolic language that is used on engineering drawings and computer-generated models. It communicates geometric dimensions and allowable tolerances for various parts. Not only is this a useful exercise for product design, it’s also helpful on the manufacturing floor because engineers and operators can quickly see the degree of tolerance that is required for each part.
