Injection mold
manufacturing
At PAWFORM, we manage and supervise projects in which the injection mold is the key element — from technical assumptions and tool design, to trials and production launch. We ensure consistency: part – mold – process, so that the tool operates stably and product quality is repeatable from the first production runs.
Areas in which
we support clients
At every stage, we focus on full transparency, providing visibility into the project and ongoing monitoring of its progress. We meet agreed deadlines.
DEVELOPMENT OF MAIN INJECTION MOLD CONCEPT
Based on project assumptions, we define the injection mold concept: tool type, target machine, manufacturing standard, and quality requirements. We also identify key risks related to product geometry, its function, and the planned production technology. This stage organizes the assumptions and forms the basis for further design work.
PRODUCT GEOMETRY OPTIMIZATION
We evaluate the part design in terms of injection mold construction and quality risks related to the injection process. We analyze product geometry for potential defects resulting from uneven wall thickness, shrinkage distribution, bottlenecks, weld lines, and gate location. We use Moldex3D rheological analysis to assess cavity filling behavior, temperature distribution across the part cross-section, and thermally loaded areas that require attention when designing the mold cooling system.
DEFINITION OF PART FORMING METHOD
We define how the part will be formed in the cavity: draft directions, parting line, critical surfaces, and necessary functional elements of the mold. At this stage, we also define assumptions for sliders, ejectors, and cores. A well-developed concept reduces the risk of costly modifications at later stages of tool manufacturing.
INJECTION MOLD DESIGN
We develop the mold design in accordance with the adopted design and technological assumptions. We verify the correctness of functional systems to ensure stable tool operation, required part quality, and the intended cycle time. This is the stage where we translate the design into a solution ready for manufacturing.
FULL INJECTION MOLDING SIMULATIONS
We perform Moldex3D simulations to validate the adopted design and technological assumptions. We analyze cavity filling behavior, the cooling system, cycle time, and risks of deformation and part defects. This allows us to identify areas requiring correction before tool manufacturing and reduce the risk of costly changes after trials.
COOPERATION WITH SURFACE FINISHING SERVICE PROVIDERS
For visual parts, we define surface finishing requirements with contractors, including the structure of forming elements and final part quality. We determine steel selection for forming components, texturing boundaries, and surfaces intended for texture application. We also verify the part’s readiness for texturing to ensure a consistent visual effect and reduce the risk of issues during manufacturing and subsequent production.
