What Goes into Providing an Injection Molding Quote at Kaysun? [VIDEO]

Requesting injection molding quotes is a standard practice for manufacturers looking to manage the costs associated with a program. Comparing injection molding price estimates may generally answer, “How much does injection molding cost?” It may even lead an OEM to select a molder based upon the bottom line.

However, price point doesn’t necessarily denote value.

How Quality Control Checks for Injection Molding Lead to Project Success [VIDEO]

Repeatable and reliable part production isn’t a given when a project is first presented to Kaysun.

Well before the injection molding equipment is made ready for a run, experts in the in-house Quality Lab are at work gaining deep insights into the part design, thoroughly examining the part practicalities and potential pitfalls, and identifying areas for improvement. Kaysun project and quality control engineers and those of the customer collaborate to share knowledge, make adjustments, and arrive at the best possible production process, tooling, and application outcome.

4 Benefits of Managing Molding Risk Probability with DfM and FMEA

Generally speaking, Design for Manufacturability (DfM) 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.

Central to maximizing these DfM benefits is prioritizing Failure Mode Effect Analysis (FMEA) within the larger plastic part analysis to assess risk probability. Identifying and addressing problems early in the product development process prevents costly issues that could impact manufacturability such as plastics selection, tight tolerances, and secondary operations.

How Injection Molders Help Find Alternatives During the Resin Shortage

The gaps between raw materials, demand, and delivery continue to define a very uncertain future for the plastics industry. Manufacturers, injection molders, and all others dependent on plastics are understandably at a loss.

Finding solutions generally requires finding replacements for nylon, acetal resins, polysulfone (PSU), polyphthalamide (PPA), polyphenylene sulfide (PPS), polyphenylene oxide (PPO), and syndiotactic polystyrene (SPS) — a task not easily completed in light of the catastrophic resin shortage.

How Injection Molders Improve Value Engineering in Manufacturing

Up until World War II, achieving necessary product functionality at the lowest cost was usually done by any means necessary. However, the war-related scarcity of materials and parts compelled General Electric engineers to find material substitutes.

Many of the substitutes reduced project costs and improved overall product performance — and the standard practice of finding cost-effective manufacturing solutions without compromising product functionality or quality was born.  Today, we know it as "value analysis" for existing parts or “value engineering" for new parts.

3 Ways Injection Molders Use Design of Experiments to Improve Processes

Custom injection molding is, by nature, highly precise. Part performance and reliability hinge on production processes that ensure accurate, consistent outcomes. Being able to deliver on these nuances is often what sets custom injection molders apart — and generally typifies molders with engineers trained in scientific molding.

5 Ways Prototype Tooling Speeds up the Production Process

A surprising number of projects are completed without using a prototype tool. The general idea is that prototype tooling is an extra, unnecessary step that increases cost and decreases development and production times.

Actually, the opposite is true. Custom injection molding done without a prototype tool typically leads to a series of required production tool adjustments that are both costly and disruptive. The perceived savings of skipping prototype tooling quickly evaporate, and the higher risk of part defect introduces the possibility of incurring legal expenses and other related costs.

Depending on the complexity of the application, prototype tooling generally accounts for about 20-40% of overall production tooling costs. It's not an insignificant investment, but one that's well worth it when you consider the advantages.

What is Injection Molding Tooling?

Injection molding tooling is at the heart of injection molding. Whether it’s a complex application or simple part, plastic injection tooling – more specifically, tooling design – determines the quality of the injection molding process and the parts produced.

Can Injection Molder and Toolmaker Alignment Determine Success?

Success in the injection molding business isn’t limited to having the right equipment or the latest technologies. It's a good start, of course, but it takes more to meet the needs of customers that require custom injection molding for complex applications completed under challenging time and cost constraints.

Custom injection molders must have top toolmakers in their supply chains that prioritize manufacturing excellence and customer service. Core to this philosophy is that toolmakers must treat the injection molders’ customers as their own.
