This consultation involves site visits when practical to see the actual production environment and constraints. We review material data sheets, product specifications, regulatory requirements, and any other relevant documentation. We also discuss customer experiences with existing equipment to identify challenges the new equipment should address.
The needs assessment document produced from this consultation provides the foundation for all subsequent design work. It specifies technical requirements, constraints, success criteria, and any preferences the customer has for equipment design.
Conceptual Design and Feasibility Analysis
Based on the needs assessment, our engineering team develops conceptual designs for the custom equipment. We typically generate multiple design alternatives when different approaches could meet the requirements, presenting the trade-offs between each approach.
For each concept, we conduct feasibility analysis considering technical viability, cost implications, implementation timeline, and risk factors. This analysis helps identify the most promising approaches and any significant challenges that need to be addressed.
We present the conceptual designs and feasibility analysis to the customer for review and discussion. This collaborative approach ensures we understand customer priorities and incorporate their feedback before committing to detailed design.
Detailed Design and Engineering
Once the conceptual approach is agreed upon, we proceed to detailed design and engineering. This phase involves creating detailed engineering drawings, performing calculations and simulations, and specifying all components and systems.
For complex custom equipment, we may perform computational fluid dynamics analysis, finite element analysis, or other engineering simulations to validate design approaches before manufacturing. These simulations help identify potential issues early and optimize design performance.
The detailed design phase includes specifying all purchased components such as motors, controls, valves, and other elements. We select components that meet performance requirements while balancing cost and reliability considerations.
Throughout the detailed design process, we maintain communication with the customer, presenting key design decisions for review and approval. This ongoing communication ensures the final design aligns with customer expectations.
Manufacturing and Quality Control

Cost Analysis for Custom Solutions
Developing custom machinery involves different cost considerations compared to purchasing standard equipment. Understanding these costs helps customers make informed decisions about custom solutions and justify the investment.
Development Costs
Custom equipment development incurs upfront costs for design engineering, testing, and specialized manufacturing processes that are not required for standard equipment. These development costs typically add 20-50% to the base cost of a standard machine of equivalent capacity.
The development cost depends heavily on the complexity of the custom requirements. Straightforward modifications to standard designs may add only 20-30% to cost, while completely new designs may add 50% or more.
Component Costs
Custom solutions often require specialized components that are more expensive than standard components. These might include custom-fabricated screw elements, specialized control systems, unique sensors, or other custom-made parts.
However, custom solutions can also reduce costs by eliminating unnecessary features that would be included in a standard machine. When a custom solution focuses on exactly what is needed, component costs may be optimized compared to purchasing over-specified standard equipment.
Timeline Costs
Custom equipment development typically requires longer lead times than purchasing standard equipment, which represents a cost in terms of delayed production capability. Standard equipment might be delivered in 2-4 months, while custom equipment may require 6-12 months depending on complexity.
However, custom equipment that precisely meets requirements can achieve better performance, higher productivity, or lower operating costs that quickly offset the delayed start. The total cost of ownership over the equipment’s lifetime often favors custom solutions when requirements are unique.
Value and Return on Investment
Custom solutions often deliver value that far exceeds the additional development costs. Better product quality, higher productivity, reduced material waste, lower energy consumption, and improved operator efficiency all contribute to economic benefits.
For many custom solutions, the return on investment can be achieved in 1-3 years through these performance improvements. Over the equipment’s lifetime, the accumulated benefits typically far exceed the initial development costs.
Cost Comparison Example
Consider a customer needing to produce a specialty compound. A standard KTE-65 twin-screw extruder might cost approximately $150,000. A custom version with specialized screw configuration for the unique material and enhanced wear protection might cost $225,000, an additional $75,000.
If the custom extruder enables 15% higher throughput due to better material processing and reduces scrap rate from 5% to 2%, the annual benefits could be substantial. Assuming $2 per kg of material value and 400 kg/h output at 6,000 hours per year, the annual production value would be $4.8 million. A 13% net improvement (15% output increase and 3% scrap reduction) represents $624,000 in annual benefit, paying back the $75,000 premium in less than 2 months.
