Molding

We specialize in implementing unique strategies, consistent and repeatable loading and unloading methods, and tolerance analysis of over-molded components to maintain proper shut offs and shot-to-shot repeatability.

Capabilities

• Over-molding of metal components such as Nitinol, Platinum or Stainless Steel
• Over-molding 1^st shot plastic components with a 2^nd shot of the same or different plastic.
• Vertical rotating tables to allow additional flexibilities for loading and unloading inserts
• Tight stack up tolerance controls for components produced across the Cretex Medical family of companies

We have the expertise to meet the unique challenges of extremely small tolerances coupled with process validations that come with molding microscopic medical parts.

Capabilities

• Part sizes as small as <0.001 grams
• Tight tolerance control on micro features
• Design for manufacturing around gate and ejection
• Features <100 microns
• Shot-to-shot repeatability of micro features using micro injection molding machines

Our investment in technology, and our advanced engineering approach, leads to shot-to-shot repeatability of micro-insert molding. We can produce very small components with complex geometries, including threads, plunging/bulkheads and holes to meet exacting requirements.

Capabilities

• In-source micro inserts for overmolding by leveraging the capabilities across the Cretex Medical family
• Tight tolerance control for shut off locations due to insourcing
• Internal automation for loading inserts with less labor and more consistent cycles

When you need excellent biocompatibility, high tensile strength, low compression set, chemical inertness, durability and sterilization compatibility, our silicone molding facilities are the right choice.

Capabilities

• 20 to 40 ton vertical
• 100 ton horizontal
• Individual components to fully integrated over-molded sub-assembly
• Semi-auto to fully automated cells
• Implantable and non-implantable LSR
• Traditional LSR over-molding with micro-molding capabilities
• Material range 20-90A durometers

Our two-shot technology gives you increased freedom in part design, so you’re not limited by assembly requirements. Two-shot molding improves quality and consistency by reducing misalignments that can result from traditional insert or over molding processes. It also eliminates the costs of additional operations, assembly and extra tool validation.

Capabilities

• Rotary two-shot machines up to 220-tons
• In-mold spin stack technology with auxiliary injection units
• Pick and place transfer two- shot capabilities for complex two- shot insert molding products
• In-house automation for complex two-shot applications
