16 Key Criteria for Healthcare Applications Six Key Considerations for Material Selection 1. Duration of Contact 2. Biocompatibility 3. Product Life Cycle 4. Sterilization Method 5. Cleaning and Disinfecting 6. Property Requirements Solvay Specialty Polymers

17 Duration of Contact How long is the device in contact with bodily fluids or surgically formed body cavity? Limited Exposure Prolonged Exposure Permanent Exposure <24 hours >24 hours <30 days >30 days Important to confirm with the supplier that their materials are offered for use in implantable devices Solvay Specialty Polymers

18 Biocompatibility Fundamental requirement Testing standards are defined by ISO 10993: and FDA G-95 Guidance document based on duration and type of contact with human body USP Class VI compliance is typically not sufficient, especially for implantable devices Does your material supplier have an Master Access File (MAF) registered with the FDA and, if so, how/when may you receive an access letter? MAF s typical for materials used in implantable devices but not typically available to those used in limited exposure devices Solvay Specialty Polymers

19 Product Life Cycle Single-Use Devices Sterilized once Cleaning & disinfecting are not required As-molded properties OR Reusable Devices Sterilized repeatedly Cleaned & disinfected repeatedly Long-term properties (up to 3+ years) Reusable devices require higher performing plastics Solvay Specialty Polymers

20 Sterilization Method Methods Steam Autoclave Pressurized steam up to 134C for 20 minutes 50 to 1,000+ cycles Common for reusable devices Ethylene Oxide Gas Disrupts microorganism s DNA to prevent reproduction For materials that degrade with heat or irradiation High-Energy Gamma Radiation Radiation kills microorganism (25 or 40 KGy) Common for single-use devices Vaporized Hydrogen Peroxide Low-temperature sterilization Cycle times 30 or 40 minutes Solvay Specialty Polymers

33 How to be Successful Designing with Plastic Shapes Avoid the common pit-falls which can lead to failures resulting in lost time, lost money, and lost confidence in your plastic design. Often times, such failures are the result of poor material selection or poor design. Reasons for machined plastic component failures? Temperature or chemical exposure Improper clearance Cracking due to impact or fatigue Unable to hold desired tolerances Material movement i.e. bowing or warping Component design with machined plastic is much different than traditional materials. Machining with Plastics is not hard. Machining with Plastics is just different versus traditional materials. Understanding a few simple tips can make the difference!

34 How to be Successful Designing with Plastic Shapes Simple Design Modifications and the Right Approach can make the difference: Machining Heat generation during machining is one of the largest problems we see and can lead to tolerance limitations, brittleness, burring, poor surface finish, and rapid tool wear. Factors critical to machining success: Fixturing techniques Proper feed-rates and tooling speeds Proper tooling and correct geometries Use of water-based coolant

35 How to be Successful Designing with Plastic Shapes Tolerance Expectations for Machined Parts: Keep the part cool during machining to maintain tolerance control. Utilize Quadrant recommended machining guidelines. For typical thermoplastics expect to hold 0.1% to 0.2% tolerance on all dimensions. For tighter tolerance control, consider rough machining (within.030 ) and allowing the part to stress relieve for 24 to 48 hrs. Extreme Finish: Vapor polished medical components.

36 How to be Successful Designing with Plastic Shapes Simple Design Modifications and the Right Approach can make the difference: Increase Strength and Toughness: Where possible, we recommend putting a radius on any sharp corners (.020 to.030 radius). When threading into plastic, always use a coated tap. Proper Running Clearance: Self-lubricated polymer bearings are maintenance free and offer extended wear life. To fully recognize these benefits, proper running clearance is critical. Get your copy now!

44 Manufacturing Process Selection When is injection molding a good choice? Higher volume >500 Low cost per part Higher initial investment - $10k or more Complex geometry Part cosmetics colors, textures Insert molding bi-material assemblies Part design strength requirements benefit from flow orientation and fiber alignment. Tight tolerances Scrap reduction PMC, LLC Confidential Information 44

45 Functionality End Use Environment Assembly Assembly techniques may dictate material selection. Production quantities The number of parts needed may influence decisions, including processing methods, mold design, material choice, assembly techniques, and finishing methods. Cost constraints Market will only bear a finite cost. Processing Processing method will effect design.

PMC, LLC Confidential Information 46

47 Part Geometry Nominal Wall Thickness Nominal Wall Thickness Selecting the proper nominal wall thickness is one of the first and most important part design decisions Maintain uniform wall thickness to minimize part warpage and dimensional control problems PMC, LLC Confidential Information 47

48 Part Geometry Nominal Wall Thickness Core out or redesign thick sections for a more uniform wall thickness When wall thickness can not be uniform, round or taper the thickness transitions to minimize molded-in stress PMC, LLC Confidential Information 48

49 Part Geometry Ribs To increase part stiffness, ribs are typically a better option than increasing nominal wall thickness Ribs widths should not exceed 80% of nominal wall to avoid causing sink marks or surface blemishes. For a given stiffness, it is better to increase the number of ribs rather than the height. For thick ribs "core out" the rib from the back to maintain a uniform wall thickness. PMC, LLC Confidential Information 49

50 Part Geometry Holes Holes are easily produced in molded parts. Core pins that protrude into the mold cavity make the holes when the part is molded. Through holes in molded parts are easier to produce than blind holes, which do not go all the way through a part. Blind holes are made by core pins supported on one end only. The pins can be deflected and pushed off center by the pressures of the molten plastic material during the molding process. PMC, LLC Confidential Information 50

51 Part Geometry Bosses Bosses are used for locating, mounting, and assembly purposes. Avoid bosses that merge into sidewalls. Use ribs and gussets for support. Avoid tall bosses required draft can cause the top of the boss to be too thin to fill or the bottom of the boss too thick. Also, long thin core pins are difficult to core properly. Consider using cores from both sides or gussets Boss wall thickness should be less than that of the nominal wall to avoid sink and warp issues. PMC, LLC Confidential Information 51

52 Injection Molding Machine/Process Overview Plastic pellets are normally dried and fed through a hopper into the reciprocating screw. The material melts as it travels forward when the screw turns. Screw movement forces the molten material into the mold After the material in the mold solidifies, the mold opens and the part is ejected. PMC, LLC Confidential Information 52

53 Moldability Moldability is the ease with which a material is processed in the part design. The key elements of the molding sequence are: Fill Pack Cool Eject PMC, LLC Confidential Information 53

54 Moldability Fill & Pack Fill The first stage of plastic injection Flow length the distance from the gate to the last area fill must be within acceptable limits for the plastic resin chosen. Excessively thin walls may develop high molding stresses, cosmetic problems, and filling problems Pack - Adding material to the mold for complete fill of the cavity and for compensating the shrinkage that occurs during cooling. PMC, LLC Confidential Information 54

55 Moldability Cool & Eject Part design has a large impact on part cooling. Uneven wall thickness will cause a cooling rate differential within the part. Differential shrink causes molded-in stress which can lead to part warp. The increased shrink of thicker wall sections can cause the formation of sink marks on the outside wall of the part or internal, non-visible voids. Eject - Cooling is complete when a dimensionally stable part can be ejected without distortion or excessive stress. PMC, LLC Confidential Information 55

56 Anatomy of an injection tool PMC, LLC Confidential Information 56

57 Tooling Considerations Gate Location Defines flow direction and length Defines weld line position Gate into the thickest sections to avoid packing problems and sink Locate gates so material flows in the direction of reinforcement structures (ribs) Consider cosmetic requirements Avoid gating into or near areas that will be subject to high levels of applied stress PMC, LLC Confidential Information 57

58 Tooling Considerations Weld Lines Holes in the nominal wall will divide the material flow into two fronts. The point at which the two flow fronts rejoin on the opposite side is called a weld line. Weaker than surrounding plastic material, especially with reinforced thermoplastics. Define gate location to keep weld lines in a low stress area of the part. Can exhibit poor cosmetics. PMC, LLC Confidential Information 58

59 Tooling Considerations Draft Draft - providing angles or tapers on product features that lie parallel to the direction of release from the mold eases part ejection. Draft all surfaces parallel to the direction of steel separation Angle walls and other features that are formed in both mold halves to facilitate ejection and maintain uniform wall thickness Additional draft is needed for textured surfaces. PMC, LLC Confidential Information 59

60 Tooling Considerations Undercuts Undercuts are design features that place portions of the mold in the way of the ejecting plastic part. Some undercuts can be stripped off of a core. Most undercuts need complex mold actions to create; however, clever part design can eliminate these expensive tooling investments by using bypassing steel or through holes PMC, LLC Confidential Information 60
