Techniques for component protective overmolding include selectively applying a protective material substantially over one or more elements coupled to a framework, forming an inner molding substantially over the framework, the one or more electrical elements coupled to the framework, and the protective material. In some examples, the inner molding is formed after the protective material has been selectively applied, forming an outer molding substantially over the inner molding and the outer molding is configured to protect the framework and to provide a surface configured to receive a pattern. Further, the outer molding may be configured to be removable if a defect is found during an inspection performed after the outer molding is formed.

Method for welding a plastic housing

케이스의 두 부품을 용접할 때 둘러싼 테두리에 따라 생성된 용융물은 미리 설계된 외곽에 의해, 다시 말하여 주로 회로기판 방향으로 유도되어 이 기판을 형태 접합식으로 고정시킨다. 본 발명은 이미 알려진 플라스틱 레이저 용접에 바탕을 두고 있다. 본 발명에서는 거기서 지정된 기본 윤곽을 변형하여 용융물이 제어되지 않고 양쪽 방향으로 분산되지 않고 의도적으로 케이스 내부 공간 방향으로 유도되도록 하였다. 이러한 개념의 장점은 회로기판을 고정하고 케이스를 밀폐할 때 단 한 번만 작업하면 된다는 점이다. 또한 회로기판의 고정면도 기존의 고온 가스 리벳에서보다 훨씬 넓다. 이때 지지면이 회로기판의 테두리 구역에만 영향을 주기 때문에 회로기판이 필요로 하는 면적도 적다. 또한 이 테두리 구역은 개별 회로기판이 패널에서 분리되므로 차단 구역으로 정의된다. 접촉면이 넓어지기 때문에 플라스틱의 유동에 의한 기본 장력의 손실은 장애가 되지 않는다. 위에서 언급한 장점 외에도 본 방법은 공정 시 상당히 안전한 바, 왜냐하면 특히 힘을 평가하여 용접 궤적을 제어하기 때문이다. 그러므로 기본 장력이 상승할 때(스토퍼가 회로기판에 놓인 후) 회로기판에 하중을 강하게 가하지 않고 용접을 중단시킬 수 있다. The melts generated along the rim of the case when welding the two parts of the case are guided mainly by means of a pre-designed enclosure, that is to say, towards the circuit board, so that the board is fixed in a form-jointed manner. The present invention is based on already known plastic laser welding. In the present invention, the basic outline designated there is modified so that the melt is intentionally guided in the direction of the space inside the case without being controlled and not dispersed in both directions. The advantage of this concept is that it only needs to be done once when fixing the circuit board and sealing the case. In addition, the fixed surface of the circuit board is much wider than in conventional hot gas rivets. At this time, since the supporting surface affects only the edge area of the circuit board, the area required by the circuit board is also small. This border area is also defined as the blocking area since the individual circuit boards are separated from the panel. Since the contact surface is widened, the loss of the basic tension due to the flow of the plastic is not a hindrance. In addition to the advantages mentioned above, this method is fairly safe in the process because it controls the welding trajectory in particular by evaluating the force. Therefore, when the base tension is increased (after the stopper is placed on ...

The resulting pipe joint is fluid-tight. PVC pipe joints meet the requirements of ASTM F1970; CPVC pipe joints meet the requirements of ASTM D2864. Such PVC and CPVC piping systems are chosen to carry cold and hot aqueous streams respectively, under pressure and elevated temperature in continuous service, both, in industrial and domestic piping systems. Such piping systems also carry more corrosive fluids for specified duration, less than 50 years.

Loose sealing structure (versions), loose seal, and packing system

FIELD: transport, package. SUBSTANCE: proposed structure comprises thermoplastic polymer and organic clay dispersed in, at least, portion of thermoplastic polymer. Said loose structure comprises sealing layer that makes sealing surface. Sealing surface may form loose seals at all temperatures within temperature range of said loose seal. Note here that seal temperature range varies from sealing initiation temperature to that, at least 100°F higher than the former. Said sealing initiation temperature varies from 170°F to 350°F. Organic clay comprises plates separated by at least 20 Angstroem units. Sealing surface features mean roughness of 1500-5000 Angstroem units. Sealing layer features modulus of tension of 500-2000 MPa. In compliance with another version, proposed structure comprises thermoplastic polymer and organic clay dispersed in, at least, portion of thermoplastic polymer. Note here that organic clay features surface area exceeding 100 m 2 /g and aspect ratio exceeding 10. Loose seal comprises sealing surface at contact with sealing back layer at all aforesaid temperatures. Note here that seal temperature range varies from sealing initiation temperature to that, at least 100°F higher than the former. Said sealing initiation temperature varies from 170°F to 350°F. Sealing surface features mean roughness of 1500-5000 Angstroem units. Sealing layer features modulus of tension of 500-2000 MPa. Packing system comprises container and loose sealing section glued to said container and provided with sealing back layer and first sealing layer. Note here that first sealing layer is arranged, at least, partially above back layer to stay in contact therewith. Said first sealing layer comprises thermoplastic polymer and organic clay dispersed in, at least, portion of thermoplastic polymer. Note also that loose sealing structure makes sealing surface to create loose seal on back layer surface at all aforesaid temperatures. Note here that seal temperature range varies from ...

Lap sealable film with a peel layer

A lap sealable film for forming bags on conventional vertical form/fill/seal equipment, in which the film comprises a peelable layer (26), a seal layer (22), and a barrier layer (24, 28). The seal layer (22) contains single site catalyzed polyethylene and is capable of sealing to the barrier layer (24). The barrier layer (24, 28) comprises a heat resistant and moisture barrier material, such as high density polyethylene or polypropylene.
