Custom Injection Molds Design for Manufacturability

Our goal is to make sure your mold is properly designed and constructed as we know our customers rely on us to provide quality solutions. We understand that mold design, mold material selection, and mold construction are essential to prudce quality molded parts. This is of particular importance with engineered and high-temperature materials. Our years of experience building molds for such applications will ensure a successful launch and continued quality production.

Each project begins with a detailed design for manufacturability (DFM) of injection molding report and is reviewed by the experienced toolmaker, mould designers, project manager, and injection molding process engineers. From this report, we will show our customer:

  • General Information about Part data such as Part dimension, part weight, plastic material
  • General Information about mold data including mold steel, mold shrinkage, feed system, gate type
  • Mould Layout and Mould Size
  • Gate Locations
  • Draft Angle Analysis
  • Wall Thickness Analysis, Thick Section, Thin Section, Ribs/Bosses to Wall Thickness Ratio
  • Parting lines
  • Lifters or slides
  • Warp Analysis
  • Weld Lines
  • Sink Areas
  • Surface Finish
  • Ejector Pin Locations
  • Tolerances
  • Shut-Off Conditions
  • Thin Tool Conditions

to understand your needs to create a mold that finds your need, you also can see how to optimize part design, our molding manufacturing solution and potentially problematic areas of your plastics parts to minimize tooling costs, reduce design changes, expedite the manufacturing process and ensure part quality.

Custom Injection Molds Manufacturing

Once the custom injection molds design has been approved, the injection mold making process begins. The elements of the custom injection molds making process change based on each client’s needs. Our experienced tool makers use Mikron high-speed CNC machines, Charmiles EDM machines, Sodick slow wire cut machines and Kent grinding machines to build custom injection molds that run automatically by the efficient design of ejection, cooling, and delegating systems. We take careful measures and the required steps to ensure your tooling produces high-quality components while maximizing the mould life.

CNC Manufacturing

Stebro Mold uses 4 vertical CNC machines throughout for a variety of applications from roughing, finish milling, and electrode manufacturing.Roughing is done on the KAFO machines. Finish milling is done on the Mikron machines, hard milling steel to HRC52. Electrode manufacturing is done on the RES.SEIKI machines with 3R fixture system.

EDM Manufacturing

Stebro Mold use 5 sets of EDM machines including 1 AgieCharmiles FORM 30. The Form 30 features the latest in no-flush EDM technology, user-friendly control and zero electrode wear combined with increased machining speed. All of our EDM machines are equipped with 3R system.

Slow Wire Cut Manufacturing

Stebro Mold uses 5 slow wire cut machines including 4 Sodick and 1 Qihong.
