# Capabilities

Review core factory capabilities for plastic, hardware and OEM manufacturing projects.

## A connected set of capabilities for moving component requirements toward repeat production.

Custom plastic and hardware components involve more than a single production step. Part geometry, material, tooling, interfaces, expected volume and quality requirements can influence one another, so they should be reviewed as a connected set of decisions.

OK TOOL focuses on component-level manufacturing for OEM projects. The relevant capabilities may include injection molding, plastic component production, hardware manufacturing, mold design and tooling, sampling, secondary operations where required, and part-specific quality checks.

The pages below explain each capability in more detail. Actual process scope, finishing options, inspection requirements and project responsibilities should be confirmed against the part requirements and quotation.

- **20+** — Years of manufacturing experience
- **Plastic + Hardware** — Our manufacturing focus
- **Tooling → Production** — Support across project stages

## Capability Directory

**Choose the manufacturing capability that matches your project need.**

Start with the task or decision in front of you. Each capability page explains the relevant manufacturing considerations, information worth preparing, and questions to resolve before production.

### Plastic Injection Molding

For custom molded parts, geometry, resin selection, tooling, production volume, and acceptance requirements must be considered together.

[Explore injection molding](/capabilities/plastic-injection-molding/)

### Plastic Component Manufacturing

For molded plastic components evaluated by function, part geometry, material, interfaces, appearance, and supply needs.

[Explore plastic component manufacturing](/capabilities/plastic-component-manufacturing/)

### Hardware Manufacturing

For custom hardware parts where drawings, material or grade, critical dimensions, finishing requirements, and order quantity define the scope.

[Explore hardware manufacturing](/capabilities/hardware-manufacturing/)

### Mold Design & Tooling

For reviewing part features, release direction, tooling assumptions, and design questions that may affect mold construction and production.

[Explore mold design & tooling](/capabilities/mold-design-tooling/)

### Prototype & Production Manufacturing

For connecting prototype or first-sample review with production readiness, approved requirements, and repeat-order references.

[Explore prototype & production](/capabilities/prototype-production-manufacturing/)

### Secondary Operations

For additional processing, finishing, or assembly steps when they are required for the part and confirmed within the project scope.

[Explore secondary operations](/capabilities/secondary-operations/)

### Quality Control

For defining part-specific checks around drawings, material, critical dimensions, appearance, function, approved samples, and repeat supply.

## How Capabilities Connect

**The right capability depends on the component and the stage of the project.**

Not every project needs every service. The useful starting point is to clarify the part requirements, identify the decisions that remain open, and then confirm which manufacturing and quality steps are required.

### 1. Define the Part Requirement
Review drawings or 3D files, material or grade, application, important interfaces, quantity, and the function the component needs to perform.

### 2. Review the Manufacturing Route
Consider part geometry, tooling status, material behavior, production volume, and whether plastic, hardware, or both component types are involved.

### 3. Align Tooling & Samples
Clarify the tooling scope and use prototype or first-sample stages to review the dimensions, fit, function, and appearance that matter.

### 4. Confirm Production Requirements
Before repeat production, align the approved part definition, expected quantity, relevant secondary operations, inspection expectations, and delivery scope.

### 5. Inspect & Maintain the Reference
Review produced parts against agreed requirements and keep the current drawing, approved sample, and acceptance criteria as references for follow-up orders.

## Quality Across Capabilities

**Quality requirements should follow the part, not a generic checklist.**

Different components require different inspection priorities. The applicable checks should be based on the drawing, material, critical dimensions, appearance, function, and other criteria agreed for the project.

### Requirement Review

Confirm the current drawing, material, critical dimensions, appearance and functional requirements before production.

### Sample Approval

Use the sample stage to review relevant dimensions, fit, function, appearance and open issues against agreed criteria.

### Final Checks

Review the characteristics that matter to the finished component using the project’s specified acceptance references.

### Repeat-Order Reference

Keep approved samples, drawing revisions and inspection expectations aligned when orders repeat or requirements change.

## Questions about choosing manufacturing capabilities.

These answers explain how to identify the appropriate starting point and what information helps define the scope of a component project.

### What manufacturing capabilities does OK TOOL cover?

The capability section covers plastic injection molding, plastic component manufacturing, hardware manufacturing, mold design and tooling, prototype and production manufacturing, secondary operations, and quality control.

### Does every project require all seven capabilities?

No. The route depends on the component and project scope. Some projects may focus on manufacturing a defined part, while others may also require tooling review, sampling, agreed additional operations or specific quality checks.

### Does OK TOOL manufacture complete end products?

The stated focus is component-level plastic and hardware manufacturing for OEM projects, rather than complete branded consumer products, tools, electrical products or equipment.

### Can an existing design be reviewed before tooling?

Drawings or 3D files can be used as the starting point to discuss geometry, material, interfaces, tooling assumptions and questions that may affect production. Any engineering review scope should be confirmed for the project.

### Can samples be reviewed before repeat production?

Sample or prototype stages can be used to check agreed dimensions, fit, function and appearance. Open issues and acceptance criteria should be clarified before the sample becomes a reference for repeat production.

### Are secondary operations automatically included?

No. Additional processing, finishing or assembly should be specified and confirmed in the project scope. The required operation, finished condition, responsibilities and acceptance criteria should be clear before order confirmation.

### How are quality requirements defined?

They should be based on the drawing, material, critical dimensions, appearance, function and other requirements agreed for the component. Specific inspection methods or standards should only be stated when verified and applicable to the project.

## Have a plastic or hardware component ready for manufacturing review?

Share the drawing or 3D file, material or grade, expected quantity, application, critical dimensions and any known appearance, functional, tooling or inspection requirements. These details help clarify which capabilities and project steps are relevant.
