Mould Manufacturing
Advanced Tooling for Precision Moulds Manufacturing
Tooling is the foundation of successful moulding, and at Shefield, we specialize in designing and managing complex injection moulds with high precision. From hot runner systems to intricate core pulls, our tooling programs are built to ensure defect-free, consistent production. With decades of experience and a global footprint, our team has worked with advanced moulds across Germany, Italy, Australia, Japan, Taiwan, Korea, and China — delivering exceptional performance and long-lasting durability.
Expertise in Tool Development & Management
Our tool development engineers play a critical role in guiding projects from concept to completion, ensuring quality and efficiency at every stage. We manage tooling programs with full control — whether in-house or with global partners — to meet the highest standards of quality, cost, and timelines.
Key focus areas include:
- Tool certification and validation
- Mould flow analysis
- Evaluation and corrective action planning
By leveraging our expertise in moulding, product development, and materials, we provide valuable insights at the design stage to enhance manufacturability and reduce lead times.
Wide Range of Tooling Capabilities
We offer a comprehensive portfolio of tooling solutions to meet diverse industry needs.
Tooling options include: Proto moulds, single & multi-cavity production moulds, hot runner systems, shuttle moulds, cartridge moulds, unscrewing moulds, and more.Material expertise covers: Aluminum (proto moulds), soft steels, hardened tool steels, beryllium inserts, and advanced finishing operations such as mirror polishing, texturing, and specialized tool coatings.
Our strong partnerships with local and offshore toolmakers allow us to offer cost-effective outsourcing options, while maintaining strict control and quality consistency.
Integrated Development & Design Support
From the earliest stage of product design, we actively collaborate with clients to determine manufacturability and performance criteria. Our complete tooling development structure includes:
- Evaluating requirements & specifying moulds
- Mould design and approval
- Tool building & trial samples
- Tool validation and process parameter freezing
- Transferring data to APQP documents
Quality management
We focus on the “prevention rather than the detection” To achieve this, we follow systematic method, – Advance Product Quality Planning – and assign a Quality Engineer to work with a project team through entire plan & define, design, manufacturing and validation cycle. Specifications for functional testing and gauging systems are established during project initiation stage. Dimensional requirements, aesthetic standards and special characteristics, SPC techniques to be used, are also defined. Once the mold is built, we conduct a process capability study on CTQs in addition to complete inspection layout to assure the specifications and requirements are on target. Some of key activities that we perform to assure quality before-hand include,
- Review all customer specifications
- Cross-functional project reviews
- Assuring all inputs to the specification
- Process and material flow charts
- Review & Approvals of tool design concepts
- Process Failure Mode and Effects Analysis (PFMEA)
- Identifying project related training needs
- Measurement System Analysis (MSA)
- Pre-production Control Plans
- Product and process capability analysis with defect detection
- CAR management
- Monitoring PPM level
The base of any quality product starts with the quality materials going into it. To ensure good quality material on time, we follow systematic vendor development & management plan. Our robust system helps us in development of suppliers which is a critical aspect of achieving a consistent product.
Metrology
In addition to complete layout inspection, we do in-process periodical inspections for critical characteristics of the product. This necessitates most consistent and accurate measurement techniques.
