The Bottom Line on Custom Injection Molding TCO vs. Per-Part Quotes


Complex applications typically require custom injection molding solutions. It’s an investment OEMs are willing to make in order to get safe, effective parts and products to market — and one that provides value beyond price point if the injection molder is focused on Total Cost of Ownership (TCO) instead of per-part pricing.

A Closer Look at Injection Molding Quotes

Quotes from injection molders do more than convey project costs. They reveal how a molder scopes and approaches complex applications, and also reflect the level of thoroughness and quality an OEM can expect from a partnership.

It’s an important differentiator to keep in mind when comparing estimates. Per-part pricing can make for an attractive quote on its face, but expenses that weren’t considered or included in the quote can ultimately have OEMs facing diminishing returns. On the other hand, inclusive TCO-focused quotes may initially reflect higher bottom line costs, but the value brought to the project and injection molding partnership merits the spend.

The Value of a TCO Approach to Custom Injection Molding

An experienced injection molder such as Kaysun understands that a project encompasses the entire lifecycle of a part. Nuanced knowledge and capabilities are essential for both accurate quotes and desired custom injection molding outcomes. TCO considerations include:

Design & Engineering

All aspects of a project are influenced by design and engineering. Collaborating with specialized injection molding engineers such as Kaysun’s Design for Manufacturability (DfM) experts validates design and production feasibility, drives materials selection, maximizes part performance, and pinpoints and addresses modifications before they result in costly rework.

Sustainability Opportunities

Optimizing DfM and related engineering goals works hand-in-hand with adhering to global sustainability standards and closer-to-home initiatives. Mindful design helps to minimize materials waste and scrap, reduce energy and water consumption, promote a smaller carbon footprint, and facilitate end-of-life part/product recycling or accelerated biodegradation.

Tooling & Equipment

Tooling is pivotal to consistent part production, and is often the most substantial cost consideration on custom injection molding projects. A molder with in-house tooling capabilities can accomplish pre-tooling design work that minimizes build-sample-evaluate-modify iterations. Likewise, having experts on-site to perform preventive maintenance on tools and related equipment pays for itself by ensuring a longer production lifespan, higher cycle rates, and less downtime.

Quality Assurance & Compliance

Without a quality benchmark, injection molding accuracy and precision become moving targets. Parts are subject to inconsistencies, defects, and failure. Regulatory compliance could also be called into question. Costs could spiral without proper quality control. The Kaysun Quality Lab brings cutting-edge technology, testing equipment, and molding experts together under one roof to facilitate cross-departmental collaborations to verify pre-production readiness, in-production process stability, and product viability.

Value-Added Services (Secondary Operations)

The more services an injection molder can provide in-house, the greater the benefit to the OEM in terms of cost-effective custom injection molding solutions. Kaysun’s breadth of value-added services promotes streamlined communication, higher product quality, lower cost, faster time to market, and rapid response time for re-design needs or market shifts.

Supply Chain Management & Logistics

Supply chain disruption has lengthy and expensive consequences. Molders that mitigate their risks through supply chain forecasting and mapping are ideal partners. OEMs that choose to shorten their supply chain through regionalized injection molding partnerships further improve flexibility and cost-effectiveness that ultimately translate to project savings.

Finding a custom injection molder that cultivates partnerships based on transparency from quoting through post-project support is a worthy investment for OEMs seeking competitive advantage.
